GG preparations are isolated from pooled normal serum by a proprietary chemical fractionation method. The gamma globulin preparations are supplied as a lyophillised powder. Purity levels as GG are analyzed by SDS PAGE or Agarose electrophoresis. These preparations are especially useful as co - precipitant in RIA methods employing polythylene glycol or ammonium sulfate precipitation steps or as protein stabilizers, or as blocker in a number of immunoassays. Useful as GG control solutions for biochemical analytical tests. These preparations reconstitute to pH 7.2±0.2
