Active Recombinant Human PDGFB Protein (Ser82-Thr190), GMP Grade, Animal-Free

• Cat.No.: PDGFB-16HG
• Product Overview: GMP recombinant human PDGF-BB protein (Ser82-Thr190) without tag was expressed in E. coli, produced using non-animal reagents in an Animal-Free laboratory and manufactured and tested under cGMP guidelines.

Specification

• Species: Human
• Source: E.coli
• Protein Length: Ser82-Thr190
• Description: This gene encodes a member of the protein family comprised of both platelet-derived growth factors (PDGF) and vascular endothelial growth factors (VEGF). The encoded preproprotein is proteolytically processed to generate platelet-derived growth factor subunit B, which can homodimerize, or alternatively, heterodimerize with the related platelet-derived growth factor subunit A. These proteins bind and activate PDGF receptor tyrosine kinases, which play a role in a wide range of developmental processes. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 17, at sites where this gene and that for collagen type 1, alpha 1 are located, are associated with dermatofibrosarcoma protuberans, a rare skin tumor. Alternative splicing results in multiple transcript variants.
• Form: Disulfide-linked homodimer
• Bio-activity: Measured in a cell proliferation assay using NR6R-3T3 mouse fibroblast cells. The ED50 for this effect is 1.5-6 ng/mL.
  The specific activity of recombinant human PDGF-BB is >7.5 x 105 IU/mg, which is calibrated against the human PDGF-BB WHO International Standard.
• Molecular Mass: Predicted Molecular Mass: 12.3 kDa (monomer)
• N-terminal Sequence Analysis: Ser-Leu-Gly-Ser-Leu-Thr-Ile-Ala-Glu-Pro
• Endotoxin: <0.01 EU/ μg of the protein by the LAL method.
• Purity: >97%, by SDS-PAGE with silver staining, under reducing conditions.
• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  A minimum of 12 months when stored at ≤ -20 centigrade as supplied. Refer to lot specific COA for the Use by Date.
