    • Introduction

      Excess adiposity is the most important risk in the development of type 2 diabetes mellitus (T2DM). Adipose tissue produces several proteins (adipocytokines) such as leptin, adiponectin, resistin, tumor necrosis factor-a, and IL-6, that modulate sensitivity and appear to play an important role in the pathogenesis, diabetes, dyslipidemia, inflammation, and atherosclerosis. Visfatin, also known as pre-B cell colony-enhancing factor (PBEF), is a cytokine that is highly expressed in visceral fat and was originally isolated as a secreted factor that synergizes with IL-7 and stem cell factors to promote the growth of B cell precursors. Visfatin homologs have been identified in carp, invertebrate mollusks, and bacteria, as well as in vertebrates, including humans and the mouse. It has been postulated to play a role in innate immunity.
      Visfatin exerts mimetic effects that are dose-dependent and quantitatively similar to stimulating muscle and adipocyte glucose transport, and in inhibiting hepatocyte glucose production. Intravenous injection of recombinant visfatin in mice decreased plasma glucose in a dose-dependent fashion. In keeping with its mimetic effects, visfatin was as effective in reducing hyperglycemia in deficient diabetic mice. Visfatin was also found to be bound to and activate receptor, causing receptor phosphorylation and the activation of downstream signaling molecules. However, visfatin did not compete for binding to the receptor, indicating that the two proteins were recognized by different regions of the receptor. Thus, visfatin might play a role in glucose homeostasis and dysregulation in biosynthesis or signal transduction, and might contribute to the pathogenesis of diabetes.

    • Synonyms

    • Physical Appearance

      Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized Visfatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Visfatin 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

      Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with 20 mM HCl at a concentration of 0.1 mg/mL, which can be further diluted into other aqueous solutions. Wait several minutes for full reconstitution and solubility.

    • Background

      About Visfatin Human


      Visfatin is a cytokine expressed in visceral fat that was originally isolated as a secreted
      element that synergized with stem cell factors and IL-7. One of its main functions is to
      enhance the development of B cell precursors.

      The cytokine is also known as the “Pre-B Cell Colony-Enhancing Factor (PBEF).” It has been
      identified in vertebrates, including mice and humans, and it’s being studied due to its link
      to inflammatory conditions, beta cell function, and cardiovascular disease.


      What’s the Function of Visfatin Human Recombinant?

      Visfatin human recombinant is produced in E. Coli. It’s a single, non-glycosylated,
      polypeptide chain that contains 466 amino acids, it’s purified by FLAG-affinity
      chromatography, and it contains a total molecular mass of 52.6 kDa.


      What Are the Main Applications of Visfatin Human Recombinant?

      The cytokine is being researched because of its involvement in glucose homeostasis,
      dysregulation in biosynthesis and signal transduction, and the pathogenesis of diabetes.
      Visfatin human recombinant is tailored exclusively for laboratory research, ensuring
      experts can get further answers regarding the cytokine’s involvement in different
      processes, including pathogenesis, diabetes, inflammation, dyslipidemia, and
      atherosclerosis.

      Findings can also help during the identification of high-risk people for cardiovascular
      disease and diabetes.

    More Info

    • Introduction

      EFNB1 is a member of the Eph family. The cell-surface proteins Ephrins split into two groups, ephrin-A and ephrin-B, based on their structure and function and perform as ligands for Eph receptors. The transmembrane EFNB1 proteins have conserved cytoplasmic tyrosine residues that are phosphorylated upon interaction with an EphB receptor. In addition, EFNB1 transduces outside-in signals by C-terminal protein interfaces which influence integrin-mediated cell attachment and migration.

There are at least four known subspecies: T. pallidum pallidum, T. pallidum pertenue, T. pallidum carateum and T. pallidum endemicum. The helical structure of T. pallidum pallidum allows it to move in a corkscrew motion through viscous mediums such as mucus. Treponema pallidum sub sp. pallidum has one of the smallest bacterial genomes at 1.14 million base pairs (Mb) and has limited metabolic capabilities, reflecting its adaptation through genome reduction to the rich environment of mammalian tissue.

    • Stability

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

    • Applications

      Treponema Pallidum protein is suitable for ELISA and Western blots, excellent antigen for detection of T. Pallidum with minimal specificity problems.

    • Specificity

      Immunoreactive with sera of T.Pallidum infected individuals.

    • Purification Method

      Treponema Pallidum protein was purified by proprietary chromatographic technique.

    More Info

    • Introduction

      PEDF is a neurotrophic protein that induces extensive neuronal differentiation in retinoblastoma cells. SerpinF1 is a potent inhibitor of angiogenesis. EPC1 doesn’t undergo the stressed to relaxed conformation transition characteristic as of the active serpins since it exhibits no serine protease inhibitory activity.
      Aqueous humour level of asymmetric dimethylarginine is correlated with PEDF in humans. ADMA and PEDF levels are increased in response to inflammation in uveitis.
      Lack of PEDF expression is a potent factor for the enhancement of tumor growth and angiogenesis in breast cancer.
      PEDF & VEGF genes contribute to the development of diabetic retinopathy.
      PEDF and VEGF structural changes in blood vessel wall play an important role in the pathophysiology of PD patients.
      PEDF-overexpressing tumors exhibited reduced intratumoral angiogenesis.
      SerpinF1 is a new promising approach for the treatment of osteosarcoma.
      Levels of the natural ocular anti-angiogenic factor SentrinF1 (PEDF) is associated with proliferative retinopathy.
      VEGF secreted by retinal pigment epithelial cells upregulates PEDF expression via VEGFR-1 in an autocrine manner.
      Sentrin-F1 concentration in the aqueous humor of diabetic patients predicts who will develop progression of retinopathy.
      PEDF blocks angiogenic effects of leptin through its anti-oxidative properties.

      It is recommended to reconstitute the lyophilized Super Leptin Antagonist in sterile water or sterile 0.4% NaHCO3 adjusted to pH 10, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    • Amino Acid Sequence

      The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg.

    • Background

      Leptin is a hormone which mainly produced by adipocytes. Leptin’s main part is to regulate long-term energy balance. Leptin is encoded by the LEP gene. Leptin receptors are expressed by various brain and peripheral cell types. leptin levels influence satiety, appetite and triggers behaviours which save energy. When leptin levels are high, the brain interprets 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.

    • Protein content

      Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.2 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

    • Introduction

      PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.

    • Introduction

      SERPINB2 is an inhibitory serpin produced primarily in keratinocytes, stimulated monocytes, and placental trophoblasts. SERPINB2 is found primarily as a 47 kDa non-glycosylated intracellular protein that is induced to be secreted as 60 kDa glycoprotein. The glycosylated and unglycosylated SERPINB2 are similarly effective as inhibitors of urokinase-type plasminogen activator (uPA), the only proven physiological target of SERPINB2.

    More Info

    • Introduction

      SERPINB5 (Maspin) is a tumor suppressor protein of the serine proteinase inhibitor family. Maspin plays a vital role in embryonic development through critical functions in cell adhesion. In addition, Maspin is present in normal breast and prostatic epithelial cells although down regulated in the particular carcinomas. SERPINB5 impedes the growth, invasion, and metastatic properties of mammary tumors as well as the invasive ability of pancreatic ductal adenocarcinoma cells. SERPINB5 being a breast tumor suppressor gene is a significant marker of the disease progression in breast neoplasms. Furthermore, high expression of maspin is linked to squamous cell carcinoma in non-small-cell lung cancer. Moreover, maspin expression has been directly linked with the biological aggressiveness of ovarian carcinoma. Maspin exhibits no serine protease inhibitory activity since it does not undergo the stressed to relaxed conformational transition typical of active serpins.

      BAFF binds to tnfrsf13b/taci and tnfrsf17/bcma. Tnfsf13/april binds to the same 2 receptors, together, they form a 2 ligands -2 receptors pathway involved in the stimulation of b- and t-cell function and the regulation of humoral immunity. A third b-cell specific baff-receptor (baffr/br3) promotes the survival of mature b-cells and the b-cell response.
      B Lymphocyte Stimulator functions as a potent B-cell growth factor in costimulation assays.
      Administration of BAFF Human recombinant to mice disrupts splenic B-cell and T-cell zones and results in elevated levels of serum immunoglobulin.

    More Info

    • Introduction

      Plasma protease C1 inhibitor (SERPING1) is a part of the serpin superfamily of serine protease inhibitors. SERPING1 plays an important role in regulating activation of both the complement and contact systems. That isdue to the fact that SERPING1 regulates the activation of complement factor C1 in addition to the activity of activated C1 by coupling with the active catalytic site at the light chains of C1r and C1s. SERPING1 insufficiency results in hereditary angioedema, which is characterized by recurrent episodes of localized angioedema of the skin, gastrointestinal mucosa or upper respiratory mucosa.
