Figure 1. Biochemical and growth factor compositions of industrial scale platelet lysate lots.
Aliquots from PL-S lots (average 18.8±2.5 liters) were tested for A) sodium, chloride, urea nitrogen, glucose, calcium, and osmolality; B) potassium, creatinine, pH, total protein and hemoglobin levels. (n=9); C) platelet derived growth factor isoform (PDGF-BB), epidermal growth factor (EGF) D) vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF). The concentration of each growth factor from 6 of 9 lots was determined by an enzyme-linked immunosorbent assay (ELISA).
