Recombinant Human PlGF-2

Description :
FAQ COA 已发表文献 PlGF-2 is an angiogenic factor that belongs to the cysteine-knot superfamily of growth factors. PlGF-2 is expressed in umbilical vein endothelial cells and placenta. It signals through the VEGFR-1/FLT1 receptor, and stimulates endothelial cell proliferation and migration. PlGF-2 also signals through Neuropilin (NP-1), and can bind with high affinity to heparin. Recombinant Human PlGF-2 is a 34.6 kDa disulfide-linked homodimeric protein of two 152 amino acid polypeptide chains. Product Properties Synonyms Placenta Growth Factor-2, PGFL Accession P49763-3 GeneID 5228 Source E.coli-derived Human PlGF-2 protein,Leu19-Arg131. Molecular Weight Approximately 34.6 kDa.

Purity > 97% by SDS-PAGE and HPLC analyses. Biological Activity Fully biologically active when compared to standard. The biologically active as determined by its ability to chemoattract human monocytes using a concentration range of 5.0-50 ng/mL. Endotoxin 0.1EU per 1g of the protein by the LAL method. Formulation Lyophilized from a 0.2 m filtered concentrated solution in PBS, pH 7.4, with 0.02 % Tween-20. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20C. Further dilutions should be made in appropriate buffered solutions.
