    Formulation

    The protein was lyophilized with no additives.

    Purity

    Greater than 97.0% as determined by analysis by RP-HPLC.

    More Info

    • Introduction

      GH-releasing peptides (GHRPs) are synthetic peptides that like GHRH effect on pituitary somatotrophs to stimulate GH release. The GHRP4 is one of several synthetic met-enkephalin analogs that owns unnatural D-amino acids. They were developed for their growth hormone (GH) releasing activity and called GH secretatogues. They lack opioid activity but are potent stimulators of GH release. These secretatogues are distinct from the growth hormone releasing hormone (GHRH or GHRF) as they share no sequence relation and derive their function through action at a completely different receptor, the ghrelin receptor.

    • Synonyms

      GHRP-4, GHRP4.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized Growth Hormone Releasing Peptide-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GHRP4 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 GHRP4 in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.

    • Amino Acid Sequence

      (D-Trp)-Ala-Trp-(D-Phe)-NH2.

    More Info

    • Introduction

      Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117(c-Kit). SCF is also known as "steel factor" or "c-kit ligand". SCF exists in two forms, cell surface bound SCF and soluble (or free) SCF. Soluble SCF is produced by the cleavage of surface bound SCF by metalloproteases. SCF is a growth factor important for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).

    • Synonyms

      Kit ligand Precursor, C-kit ligand, SCF, Mast cell growth factor, MGF, SF, KL-1, Kitl, DKFZp686F2250.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized KIT ligand although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SCF 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 Stem Cell Factor in sterile 18MΩ-cm H2O 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 Met-Glu-Gly-Ile-Cys.

    • Protein content

      Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.52 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of Stem Cell Factor as a Reference Standard.

    More Info

    • Introduction

      Cytohesin 3 (CYTH3) belongs to the PSCD family, whose members have identical structural organization which consists of an N-terminal coiled-coil motif, a central Sec7 domain, and a C-terminal pleckstrin homology (PH) domain, and seem to mediate the regulation of protein sorting and membrane trafficking. CYTH3 is involved in the regulation of Golgi structure and function, and it might have a physiological role in regulating ADP-ribosylation factor protein 6 (ARF) functions, in addition to acting on ARF1.

    More Info

    • Introduction

      Vascular endothelial growth factor is an important signaling protein involved in both vasculogenesis and angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/ macrophagemigration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesisand cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
      Elevated levels of this protein are linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

    • Introduction

      The epidermal growth factor receptor (EGF R) subfamily of receptor tyrosine kinases comprises four members: EGF R (also known as HER1, ErbB1 or ErbB), ErbB2 (Neu, HER-2), ErbB3 (HER-3), and ErbB4 (HER-4). All family members are type I transmembrane glycoprotein that has an extracellular domain which contains two cysteine-rich domains separated by a spacer region that is involved in ligand-binding, and a cytoplasmic domain which has a membrane-proximal tyrosine kinase domain and a C-terminal tail with multiple tyrosine autophosphorylation sites. The human EGF R gene encodes a 1210 amino acid (aa) residue precursor with a 24 aa putative signal peptide, a 621 aa extracellular domain, a 23 aa transmembrane domain, and a 542 aa cytoplasmic domain. EGF R has been shown to bind a subset of the EGF family ligands, including EGF, amphiregulin, TGF-a , betacellulin, epiregulin, heparin-binding EGF and neuregulin-2 in the absence of a co-receptor. Ligand binding induces EGF R homodimerization as well as heterdimerization with ErbB2, resulting in kinase activation, tyrosine phosphorylation and cell signaling. EGF R can also be recruited to form heterodimers with the ligand-activated ErbB3 or ErbB4. EGF R signaling has been shown to regulate multiple biological functions including cell proliferation, differentiation, motility and apoptosis. In addition, EGF R signaling has also been shown to play a role in carcinogenesis.

    • Introduction

      Cardiotrophin-like cytokine factor 1 (CLCF1) is a member of the interleukin 6 family of cytokines, which are involved in cell signaling via phosphorylation of gp130. CLCF1 has a sequence of 225 amino acids with a 27 aa signal peptide, having a molecular mass of 22kDa in the mature form, and the maximum homology to cardiotrophin-1 and ciliary neurotrophic factor. CLCF1 is actively secreted from cells by forming a complex with soluble type I CRLF1 or soluble CNTFR. Defects in the CLCF1 gene cause cold-induced sweating syndrome 2 (CISS2). The CISS2 syndrome is typified by profuse sweating after exposure to cold as well as congenital physical abnormalities of the head and spine.

    • Background

      Cardiotrophin-Like Cytokine Factor 1 Human Recombinant: A Significant Player in Neuronal Development and Immune Regulation

      Cardiotrophin-like cytokine factor 1 (CLCF1) has emerged as a crucial player in neuronal development and immune regulation. As a heterodimeric neurotropic cytokine, CLCF1 in complex with cytokine-like factor-1 (CLF-1) has demonstrated vital roles in neuronal development. Studies show that mice lacking this heterodimer exhibit reduced motor neurons and die shortly after birth due to suckling defects. In humans, mutations in the genes encoding for CLCF1 and CLF-1 manifest as Sohar-Crisponi or cold-induced sweating syndrome, with individuals at high risk of early death​1​.

      CLCF1 also exhibits a significant role in the regulation of hematopoiesis, particularly skewing towards myeloid cell differentiation. It has been demonstrated that in mice, CLCF1 promotes B-cell expansion, enhances humoral responses, and triggers autoimmunity. Further, CLCF1 administration resulted in an increase in circulating myeloid cells, along with augmented hematopoietic progenitor cells in the bone marrow. These findings underscore CLCF1's crucial role in modulating the immune system, particularly in the context of bonemarrow transplants and recovery following sub-lethal irradiation​2​.

      Interestingly, CLCF1 is a member of the IL-6 family of cytokines, known for their significant roles in immune regulation and stem cell biology. Like other family members, CLCF1 is secreted as a composite cytokine with CRLF1 and signals through the heterodimerization of the signaling chains LIFRβ and gp130. This suggests overlapping functions with leukemia inhibitor factor (LIF), another IL-6 family member. Expression of CLCF1 is documented in lymph nodes, spleen, and circulating lymphocytes, further establishing its role in immune modulation. However, the comprehensive implications of CLCF1 in immune regulation and hematopoiesis remain an active area of investigation​3​.

      In summary, Cardiotrophin-like cytokine factor 1 human recombinant represents a promising area of research with potential therapeutic implications in neurodevelopmental disorders and immune regulation.

      What is the molecular weight/Mw of CLCF Protein?
      CLCF Protein has a total Mw of 24.6kDa.

      What is the source or expression system of CLCF Protein?

    More Info

    • Introduction

      Epiregulin is part of the EGF family. Epiregulin functions as a ligand of EGFR, as well as a ligand of most members of the ERBB (v-erb-b2 oncogene homolog) family of tyrosine-kinase receptors.Epiregulin is expressed mostly in the placenta and peripheral blood leukocytes and in specific carcinomas of the bladder, lung, kidney and colon. Epiregulin stimulates the proliferation of keratinocytes, hepatocytes, fibroblasts and vascular smooth muscle cells. Epiregulin inhibits the growth of several tumor-derived epithelial cell lines. Human Epiregulin is initially synthesized as a glycosylated 19.0 kDa transmembrane precursor protein, which is processed by proteolytic cleavage to produce a 6.0 kDa mature secreted sequence.

    • Synonyms

      EREG, Epiregulin, ER.

    • Physical Appearance

    Description

    FGF2 Thermostable is a stabilized form of FGF2 growth factor which enables a novel method to produce FGF2-dependent cell cultures more efficiently, having less media changes. FGF2 Thermostable can maintain its biological activity even after five days at 37°C. The increase in the stability of FGF2 in cell-culture enables a more homogenous, undifferentiated stem cell culture, while saving scientists crucial time and money, as frequent supplementation of FGF-basic and the everyday medium change is not necessary. Thermostable FGF-2 is a hyperstable protein. The Thermal stability of the protein is increased by 15°C compared to the wild-type FGF-2. Thermostable FGF-2 is more than 5-times prolonged half-life in human cell culture incubated at 37°C. The FGF-2 Thermostable protein is engineered with fully retained biological function and has no harmful stabilizing additives.Thermostable FGF2 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 154 amino acids and having a total calculated molecular mass is 17.2kDa.

    • Introduction

      GH-releasing peptides (GHRPs) are synthetic peptides that like GHRH effect on pituitary somatotrophs to stimulate GH release. The GHRP1 is one of several synthetic met-enkephalin analogs that owns unnatural D-amino acids. They were developed for their growth hormone (GH) releasing activity and called GH secretatogues. They lack opioid activity but are potent stimulators of GH release. These secretatogues are distinct from the growth hormone releasing hormone (GHRH or GHRF) as they share no sequence relation and derive their function through action at a completely different receptor, the ghrelin receptor.

    More Info

    • Introduction

      Omentin is a recently recognized gene highly localized to the mental tissue (visceral adipose tissue). Omentin is present in the stromal vascular cells in the adipose tissue rather than in the adipocytes. Omentin is predominantly expressed in the visceral adipose tissue than the subcutaneous tissue, with the omentin mRNA being 150 times higher in the visceral adipose tissue. Omentin has also been detected in human blood using western blot analysis, and seems to increase INSstimulated glucose uptake in 3T3-L1 adipocytes in mice. Omentin seems to increase Akt phosphorylation irrespective of INS presence. Its role in glucose metabolism and obesity remains to be described; an INS-sensitizing action is possible.Differences in Omentin expression has been noted in adipose tissue from normals and patients with inflammatory bowel disease although its significance is unknown.
