Application: An extract of bovine neural tissue containing growth promoting factors for vascular endothelial cells of mammalian origin. ECGS has also been reported to be beneficial as a media supplement for the fusion and growth of hybridoma cells in monoclonal antibody production.
Analysis Note: The proliferative activity of ECGS is tested in culture using fetal bovine heart endothelial cells (ATCC CRL 1395) seeded at low density. The EC50 is defined as the effective concentration of growth factor that elicits a 50% increase in cell growth in a cell based bioassay.
Preparation Note: Endothelial cell growth supplement (ECGS) is an extract of bovine neural tissue containing growth promoting factors for vascular endothelial cells of mammalian origin. Endothelial cell growth supplement is prepared using a modification of the method of Maciag, et al., and is lyophilized from a sterile solution containing NaCl and streptomycin sulfate.
