Pooled Human Complement Serum 1ml - Human Complement Serum is a complex mix of serum proteins which are activated sequentially when antibodies in blood with immunity interact with the corresponding antigens. Complement proteins will quickly degrade if the serum is not prepared and stored correctly. Our complement-preserved serum is freshly collected aseptically and kept cold, and then flash-frozen to prevent degradation of complement activity.
