Product Description

Donkey IgG Fractionated Purified

Donkey IgG Fractionated Purified preparations are isolated from pooled normal donkey serum by a proprietary fractionation method. The immunoglobulin preparations are supplied as a liquid. Purity levels are 97 percent IgG as analyzed by SDS-Page. These preparations are especially useful as a co-precipitant in RIA methods employing polyethylene glycol or ammonium sulfate precipitation steps, or as a protein stabilizer blocker in a number of immunoassays. These preparations are also useful as IgG control solutions for biochemical analytic tests. Immunoglobulin preparations are provided at pH 7.2.
