Adult bovine serum (ABS) is collected from adult cows. The serum is separated from the blood of adult cows more than 12 months old by mechanical defibrination process. A 9635 Adult bovine serum, heat inactivated sterile filtered (OTTO) is heat inactivated adult bovine serum. Heat
inactivation is done to destroy heat labile components such as complement that can lead to complement mediated celllysis. Complement proteins, antibodies and enzymes present in the serum are inactivated by heat inactivation.
A 9635 Adult bovine serum, heat inactivated sterile filtered (OTTO) used to supplement basal cell culture media to boost the growth and proliferation of multiple cell types. ABS is not recommended for hybridomas, embryonic stem cells and other fastidious cell types.
