Human PDGF-BB Recombinant Protein #50611

    Product Information

    Storage

    Human PDGF-BB Recombinant Protein is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/mL which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage.

    Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles if storing reconstituted material at -20ºC to -80ºC.

    Activity The bioactivity of recombinant hPDGF-BB was determined in a 3T3 cell proliferation assay. The ED50 of each lot is less than or equal to 2 ng/mL.

    Source / Purification

    Recombinant human PDGF-BB was expressed in E. coli and is supplied in a lyophilized form.

    Background

    PDGF-BB is a cystine-linked homodimer PDGF family member with key roles in development, cell proliferation, cell survival, and angiogenesis (1,2). PDGF-BB is expressed by vascular endothelium, megakaryocytes, and Leydig cells (2). PDGF-BB targets pericytes, fibroblasts, monocytes, and other cell types (1-3). PDGF induces fibroblast growth and migration (3) and is a chemoattractant for monocytes and granulocytes. Precursor PDGF-BB is cleaved intracellularly to generate a form that contains a carboxy-terminal stretch that serves to retain PDGF-BB in the extracellular matrix. In a second cleavage event, the carboxy-terminal stretch is removed extracellularly to generate mature PDGF-BB (1,2). PDGF-BB binds to PDGFRβ and induces receptor dimerization. Signaling is through the PI3K/Akt, JNK, and PLCγ pathways (1,2). PDGF-BB may have a role in some cancer types (2).
