    Description

    PMSG is a complex glycoprotein obtained from the serum of pregnant mares. This 43-63 kda protein is capable of supplementing and being substituted for the follicle stimulating and interstitial cell-stimulating hormone of the anterior pituitary gland in both the male and female. Thus PMSG-Intervet stimulates development of the ovarian follicle in the female.

    Source

    Serum of pregnant mares.

    Formulation

    The PMSG was lyophilized with no additives.

    More Info

    • Introduction

      PMSG Hormone is a well know used hormone together with progestogen to increase ovulation just before to artificial insemination. PMSG hormone is a placental glycoprotein produced from the serum of pregnant mares. PMSG comprises of an alfa subunit and a beta subunit. PMSG hormone is secreted from endometrial cups within the pregnant mare uterus aging from 40 to 130 days into their maturation, and once extracted, it can been used to promote artificially estrus in female animals. These assemblies produce PMSG hormone to induce mare's ovarian and repsouctive structures. PMSG can induce the growth of follicles by ovaries and results in ovulatation. PMSG hormone has an about a 4 day half-life of bioactivity in species other than horses. The extended biological activity can cause ovarian stimulation and ovulation. However, PMSG use alone often causes cystic ovarian disease because of the unrestrained ovarian stimulation and due to the sugar molecules which decrease clearance of the hormone. PMSG is more likely to be used than other pituitary hormones due to the extended circulatory half-life. PMSG solely exhibits luteinizing hormone like activity, however in other animal classes it has FSH & LH like activity.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized PMSG although stable at room temperature for 3 weeks, should be stored between 2-8°C.

    • Solubility

      It is recommended to reconstitute the lyophilized PMSG in sterile 18M-cm H2O at a concentration of 1000 IU/ml, which can then be further diluted to other aqueous solutions.

    More Info

    • Introduction

      BDNF promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. BDNF is a major regulator of synaptic transmission and plasticity at adult synapses in many regions of the cns. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (ltp), long-term depression (ltd), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability.

    • Synonyms

      Brain-Derived Neurotrophic Factor, BDNF, MGC34632.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized BDNF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BDNF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

    • Solubility

      It is recommended to reconstitute the lyophilized BDNF in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    More Info

    • Introduction

      Thymosin is a hormone secreted from the thymus. Its primary function is to stimulate the production of T cells, which are an important part of the immune system. Thymosin also assists in the development of B cells to plasma cells to produce antibodies. The predominant form of thymosin, thymosin b4, is a member of a highly conserved family of actin monomer-sequestering proteins. b-thymosins are the primary regulators of unpolymerized actin, and are essential for maintaining the small cytoplasmic pool of free G-actin monomers required for rapid filament elongation and allowing for the flux of monomers between the thymosin-bound pool and F-actin.

    • Background

      Thyroglobulin, a glycoprotein primarily produced in the thyroid gland, stands at the center of thyroid hormone synthesis. Comprising a series of tyrosine residues, thyroglobulin serves as the scaffold upon which thyroid hormones are assembled. Beyond its pivotal role in thyroid physiology, thyroglobulin has garnered significant attention in the realm of thyroid disease diagnostics, offering valuable insights into thyroid function and disorders. This research delves into the intricacies of thyroglobulin human recombinant protein, exploring its biochemical properties, physiological significance, and its crucial applications in both clinical and research settings.

      Structural Complexity of Thyroglobulin:

      Thyroglobulin is a large, dimeric protein boasting an intricate structure composed of multiple domains. Within its structure lie tyrosine residues crucial for iodine incorporation, a process fundamental for thyroid hormone synthesis. Its size and complexity reflect the sophistication of thyroid hormone production, as thyroglobulin acts as a reservoir for thyroid hormones within the thyroid follicles.

      Physiological Significance in Thyroid Function:

      Thyroglobulin plays a central role in the synthesis of triiodothyronine (T3) and thyroxine (T4), the thyroid hormones essential for regulating metabolism and overall body homeostasis. During thyroid hormone synthesis, thyroglobulin is secreted into the follicular lumen, where it undergoes iodination and subsequent proteolysis, releasing T3 and T4. This process highlights the indispensable nature of thyroglobulin in thyroid hormone production, making it a key biomolecule in thyroid physiology.

    More Info

    • Introduction

      Hepatitis B is one of a few known non-retroviralviruses which employ reverse transcriptionas a part of its replication process. (HIV, a completely unrelated virus, also uses reverse transcription, but it is a retrovirus.) HBV invades the cell by binding to surface receptor and become internalized. The viral core particles then migrate to the hepatocyte nucleus and the partially double-stranded, relaxed circular genomes (RC-DNA) are repaired to form a covalently closed circular DNA (cccDNA), which is the template for viral genomic and sub-genomic RNAs by cellular RNA polymerase II. Of these, the pregenomic RNA (pgRNA is selectively packaged into progeny capsids and is then reverse-transcribed into new RC-DNA. The core can either bud into the endoplasmic reticulum to be enveloped or exported from the cell or recycled back into the genome for conversion to cccDNA.

    • Stability

      HBV Core protein although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.

    • Background

      Neurofilament light chain (NEFL) is a critical component of the neuronal cytoskeleton, primarily found in neurons of the central and peripheral nervous systems. While extensive research has been conducted on NEFL in human and rodent models, the study of NEFL in bovine nervous tissues is an emerging area with potential for advancing our understanding of neuronal biology in larger mammals and its applications in veterinary medicine and neurobiology.

      Bovine nervous tissues, such as the brain and spinal cord, are of particular interest due to their relevance in cattle health and the food industry. This research aims to provide a comprehensive exploration of NEFL in bovine nervous tissues, elucidating its functions, structural significance, and potential applications.

      The primary objective of this research is to elucidate the role of NEFL in bovine nervous tissues, particularly in maintaining the structural integrity of neurons and axons. In vitro and ex vivo experiments, utilizing bovine neuronal cell cultures and tissue specimens, will be conducted to investigate how NEFL contributes to neuronal morphology, axonal transport, and neuronal resilience. Understanding these mechanisms is fundamental for deciphering the complexities of neuronal biology in bovine species.

      The second objective is to assess the relevance of bovine NEFL in veterinary medicine. Studies involving bovine models will be conducted to evaluate the impact of NEFL mutations or variations on neuronal health, disease susceptibility, and neurodegenerative conditions. These investigations may provide valuable insights into potential applications in cattle health and the development of diagnostic tools for neurological disorders.

      The third objective is to explore the potential applications of bovine NEFL in neurobiology and biotechnology. Research will investigate the use of bovine NEFL-expressing cells as models for studying neuronal-related diseases and for developing tissue engineering approaches for veterinary medicine and biotechnology.

      By delving into the functions and roles of NEFL in bovine nervous tissues, this research aims to expand our knowledge of neuronal biology, its implications for veterinary medicine, and its potential applications in neurobiology and cattle health

    • Background

      Leptin is a~16 kDa protein which is encoded by the obese gene. Leptin is a hormone which participates in regulating body weight, reproductive function and metabolism. leptin is expressed predominantly by adipocytes, which supports the idea that body weight is sensed as the total mass of fat in the body. Smaller amounts of leptin are also secreted by cellsin the epithelium of the stomach and in the placenta. Leptin receptors are highly expressed in areas of the hypothalamus which regulates body weight, as well as in T lymphocytes and vascular endothelial cells.

      Leptin is mainly produced by adipocytes. Leptin’s main part is to regulate long-term energy balance. Leptin is encoded by the LEP gene. Leptin effects mostly on leptin receptors in the cell mambrane of various cells in the human body. The leptin receptor can be found on a various cell types. The leptin receptor is a single-transmembrane-domain type 1 cytokine receptor. leptin levels influence satiety, appetite and triggers behaviours which save energy. High leptin levels are interpreted by the brain that energy reserves are high, whereas low leptin levels means that energy reserves are low, in the process adapting the organism to starvation through a variety of metabolic, neurobiochemical, endocrine and behavioral change.

    More Info

    • Introduction

      Endothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. The flt-1 gene was first described in 1990. The receptor contains seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular splited tyrosine kinase domain. Compared to VEGFR-2 the Flt-1 receptor has a higher affinity for VEGF but a weaker signaling activity. VEGFR-1 thus leads not to proliferation of endothelial cells, but mediates signals for differentiation. Interestingly a naturally occuring soluble variant of VEGFR-1 (sVEGFR-1) was found in HUVE supernatants in 1996, which is generated by alternative splicing of the flt-1 mRNA. The biological functions of sVEGFR-1 still are not clear, but it seems to be an endogenous regulator of angiogenesis, binding VEGF with the same affinity as the full-length receptor.

    More Info

    • Introduction

      Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.
      The protein encoded by this gene, pre-angiotensinogen or angiotensinogen precursor, is expressed in the liver and is cleaved by the enzyme renin in response to lowered blood pressure. The resulting product, angiotensin I is then cleaved by angiotensin converting enzyme (ACE) to generate the physiologically active enzyme angiotensin II. The protein is involved in maintaining blood pressure and in the pathogenesis of essential hypertension and preeclampsia.

    • Synonyms

      Angiotensinogen, Serpin A8, ANHU, SERPINA8.

    • Physical Appearance

    • Introduction

      The Argonaute protein is part of the RISC or RNA-induced silencing complex, as so, the protein has a key part in the slicing processes of RNA. The RNA interference (RNAi) is being held by RISC. Small non-coding RNA fragments bond to the Argonaute proteins, through base pairing, eventually leads to the cleavage of messenger RNA or translation suppression.

    • Synonyms

      Protein argonaute-2, Argonaute2, hAgo2, Argonaute RISC catalytic component 2, Eukaryotic translation initiation factor 2C 2, eIF-2C 2, eIF2C 2, PAZ Piwi domain protein, PPD, AGO2, EIF2C2, Protein slicer.

    • Physical Appearance

      Filtered colorless solution.

    • Stability

      Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
