重组人血管内皮生长因子受体3 Fc嵌合体/FLT4 Fc Human_详细资料

产品信息 重组人血管内皮生长因子受体3 Fc嵌合体/FLT4 Fc Human 产品编号：PKA-245 产品规格：2μg/10μg/1mg Catalogue Number PKA-245 Synonyms Tyrosine-protein kinase receptor FLT4, PCL, FLT41, FMS-like TYROSINE KINASE 4, VEGFR-3. Introduction All three VEGF receptors belong to the class III subfamily of receptor tyrosine kinases (RTKs) characterised by the seven immunoglobulin-like loops in the extracellular domain. The expression of VEGFR-1 to -3 is almost exclusively restricted to hematopoietic precursor cells, vascular and lymphatic endothelial cells and to the monocyte/macrophage lineage. They play key roles in vasculogenesis, hematopoiesis, angiogenesis and lymphangiogenesis. The FLT-4 cDNA encodes a 1298 amino acid (aa) residue precursor protein with a 23 aa residue signal peptide. Mature VEGFR-3/FLT-4 is composed of a 751 aa residue extracellular domain, a 22 aa transmembrane domain and a 482 aa residue cytoplasmic domain. Both VEGF family members VEGF-C and VEGF-D have been shown to bind and activate VEGFR-3/FLT-4. The Flt-4 gene is widely expressed in the early embryo but becomes restricted to the lymphatic endothelial a latter stages of development. It is important for lymphangiogenesis. Description Soluble FLT4 Human Recombinant fused with the Fc part of human IgG1 produced in baculovirus is a monomeric, glycosylated, polypeptide containing 774 amino acids and having a molecular mass of 260 kDa. The soluble receptor protein contains only the first 7 extracellular domains, which contain all the information necessary for ligand binding. The FLT4 Fc Chimera is purified by proprietary chromatographic techniques. Source Insect Cells. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Formulation FLT4 Fc Chimera was lyophilized from a concentrated (1 mg/ml) sterile solution containing no additives. Solubility It is recommended to reconstitute the lyophilized FLT4 Fc Chimera in sterile water not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. Stability Lyophilized FLT4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FLT4 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. Purity Greater than 90.0% as determined by(a)Analysis by RP-HPLC. (b)Analysis by SDS-PAGE. Biological Activity Measured by its ability to bind recombinant rat VEGF-C in a functional solid phase binding assay. Immobilised recombinant human VEGFR-3/FLT-4 at 5 μg/ml can bind recombinant rat VEGF-C in a linear range of 8-500 ng/ml. Usage ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
