Detailed product information

Background information

Platelet-derived growth factor-BB (PDGF-BB) is a dimeric protein composed by two identical B subunits, it belongs to the PDGF family together with the two receptors PDGFRα and PDGFRβ. PDGF-BB binds PDGFRβ with the highest affinity. It regulates mesenchymal cell growth, morphogenesis, and migration, especially during angiogenesis and glial cell proliferation. A dysregulation of PDGF was shown in diseases such as diabetes, and in deficit of bone formation and reparation. Human PDGF-BB IS is an engineered PDGF-BB variant retaining the same biological properties as natural accurring PDGF-BB.

We measure the biological activity of each batch of MACS Premium-Grade Cytokines and state the results in the Certificate of Analysis (CoA). Based on the lot-specific activity, exact doses of active cytokine can be applied to cell culture experiments. This allows for reproducible cell culture conditions without the need for time-consuming lot-to-lot testing.

Quality description

Research-grade

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.

Premium-grade

cytokines offer the convenience of high and well-defined biological activities and allow exact unit dosing for demanding applications. The biological activity is determined after lyophilization and reconstitution, and normalized to WHO/NIBSC standards whenever available. In general, endotoxin levels are <0.01 ng/μg (<0.1 EU/μg), and purities are >97%. Lot-specific activities are stated in the Certificate of Analysis (www. miltenyibiotec.com/certificates).
