Fetal Bovine Serum (FBS), also known as Fetal Calf Serum (FCS), is the most widely used growth supplement for cell culture media due to its high content of embryonic growth-promoting factors. KEL Biotech's  FBS reagents undergo the most stringent quality control screening and validation standards to ensure high quality and consistent batches with minimal variability.
       All of KEL’s FBS reagents meet and exceed approved compliance validation specifications. All sera undergo a methodical and comprehensive list of physicochemical, microbiological, and biological performance testing procedures. Each batch of FBS is fully documented and traceable from the source of origin to final filtration.

       Heat inactivation of serum is performed by raising the temperature of the serum to 56ºC and maintaining that temperature for 30 minutes. Heat inactivation is the method of choice to destroy complement proteins activity.
