Recombinant Human Platelet-Derived Growth Factor Beta Polypeptide

Cat. No.: PDGFB-661H
Product Overview: Recombinant PDGFB isa disulfide-linked homodimeric protein consisting of two 109 amino acidresidue subunits. Recombinant PDGFB migrates due to glycosylation as anapproximately 32 kDa protein under non-reducing conditions and as 16kDa underreducing conditions in SDS-PAGE, and was lyophilized from a 0.2 μm filtered0.02M acetic acid solution pH 6.5.
Description: PDGFB is synthesizedmainly by megakaryocytes. It is stored in the alpha granules of plateletsfrom which it is released after cell activation of platelets. Platelets synthesizea mixture of the three possible isoforms (BB,AB,AA)while fibroblastsstimulated with EGF synthesize AA homodimers.
Source: Human
Host: Saccharomycescerevisiae
Purity: >98%, asdetermined by SDS-PAGE and HPLC.

Molecular Weight: Human PDGFB,generated by the proteolytic removal of the signal peptide and propeptide,the molecule has a calculated molecular mass of approximately 16 kDa.
Biological Activity: Activity wasdetermined by the ability to induce chemotaxis of purified eosinophils atconcentrations ranging between 50-100 ng/ml.
Endotoxin: TheED(50) was determined by the dose-dependent proliferation of Balb/c 3T3cells.The expected ED50 for this effect is 1.0-3.0 ng/ml, corresponding to1x106 IU/mg.
Reconstitution: A quick spin of thevial followed by reconstitution in distilled water to a concentration notless than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage: Thelyophilized protein is stable for at least 2 years from date of receipt at-20°C. Upon reconstitution, this cytokine can be stored in working aliquotsat 2°C - 8°C for one month, or at -20°C for six months, with a carrierprotein without detectable loss of activity. Avoid repeated freeze/thawcycles.
