Specifications

PlGF-1 is an angiogenic factor that belongs to the cysteine-knot superfamily of growth factors. PlGF-1 is expressed in placental tissues, colon and mammary carcinomas.It signals through the VEGFR-1/FLT1 receptor and stimulates endothelial cell proliferation and migration.Recombinant human PlGF-1 is a 29.7kD disulfide-linked homodimeric protein of two 132 amino acid polypeptide chains.

Storage and StabilityStore lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein.
