Human Serum AB
Human serum AB has been proven to grow many human cell lines at a faster rate and with a smaller percentage of serum than mixed blood group serum.
Human serum AB is prepared from units of U.S. source plasma using only male AB blood group donors meeting health requirements established by 21CFR 640, subpart G. All approved donor units are tested and found non-reactive for Syphilis per 21CFR640.65 by FDA approved methods. Each source donor unit used is further tested and found negative for HBsAg (Hepatitis B Surface Antigen), anti-HCV (anti-Hepatitis C Virus), anti-HIV-1/2 (anti-Human Immunodeficiency Virus Type 1 and 2), and HIV-1 antigen or HIV-1 NAT by FDA approved tests. The final serum product undergoes extensive quality control testing before it is released for distribution.

Normal Human Serum
Normal human serum, also referred to as mixed blood group serum, in some applications can be used as a lower cost alternative to human serum AB.
Normal human serum is prepared from units of U.S. source plasma using male and female donors of all blood groups meeting health requirements established by 21CFR 640, subpart G. All approved donor units are tested and found non-reactive for Syphilis per 21CFR640.65 by FDA approved methods. Each source donor unit used is further tested and found negative for HBsAg (Hepatitis B Surface Antigen), anti-HCV (anti-Hepatitis C Virus), anti-HIV-1/2 (anti-Human Immunodeficiency Virus Type 1 and 2), and HIV-1 antigen or HIV-1 NAT by FDA approved tests. The final serum product undergoes extensive quality control testing before it is released for distribution.
