Newborn bovine serum is obtained from calves about 2 weeks old. Newborn bovine serum contains more immunoglobulin and protein than fetal bovine serum, which is an economical and effective substitute for fetal bovine serum. Serum is usually used as an additive for cell growth, which has many functions and uses, such as: it is rich in macromolecular proteins and low molecular weight nutrients as an additional source of amino acids, carbohydrates and vitamins; Improve the buffering capacity of the medium; Can combine or neutralize toxic components; Reduce cell oxidative stress and reduce cell apoptosis; Provide growth-promoting factors to help cells adapt to the culture environment. The thermal inactivation of serum is accomplished by raising the serum temperature to 56℃ and keeping the temperature for 30 minutes. Thermal inactivation can destroy complement and ensure that cells will not crack when combined with antibodies.

Newborn bovine serum provides many of the same nutrients as fetal bovine serum. The levels of protein and immunoglobulin are slightly higher, but there are fewer growth factors, which is suitable for culturing cells that are easy to culture or have low requirements on culture environment.

Manufactured under ISO 13485 QMS and in compliance with applicable cGMP guidelines.
