    Physical Appearance
    Sterile Filtered White lyophilized (freeze-dried) powder.
    Formulation
    Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
    Endotoxin
    Less than 1 EU/μg of rHuPDGF-BB as determined by LAL method.
    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 ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
    Stability & Storage
    Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
    - 12 months from date of receipt, -20 to -70 °C as supplied.
    - 1 month, 2 to 8 °C under sterile conditions after reconstitution.
    - 3 months, -20 to -70 °C under sterile conditions after reconstitution.
    Usage
    This material is offered by Shanghai PrimeGene Bio-Tech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.

    Background
    Platelet-derived growth factor (PDGF) presenting in serum but absent from plasma was first discovered in animal study by Lynch and co-workers in the late 1980s. It is a disulfide-linked dimer consisting of two peptides-chain A and chain B. PDGF has three subforms: PDGF-AA, PDGF-BB, PDGF-AB. It is involved in a number of biological processes, including hyperplasia, embryonic neuron development, chemotaxis, and respiratory tubule epithelial cell development. The function of PDGF is mediated by two receptors (PDGFR-α and PDGFR-β).
