Equitech-Bio's purified immunoglobulin (Ig) preparations are isolated from pooled normal serum by a proprietary chemical fractionation method.

The immunoglobulin preparations are supplied as a lyophilized powder but may be supplied as a liquid upon request.

Purity levels are 97% Ig as analyzed by SDS-Page. These preparations are especially useful as co-precipitant in RIA methods employing polyethylene glycol or ammonium sulfate precipitation steps or as a protein stabilizer or blocker in a number of immunoassays.

These preparations are also useful as IgG control solutions for biochemical analytical tests and as a heterophile blocker.

Immunoglobulin preparations reconstitute to pH 7.2 ± 0.2 . Gamma globulin preparations are also available upon request.
