Bovine Immunoglobulin G and Applications


Immunoglobulins, or Gamma Globulins, are plasma proteins with broad binding capacity. Produced by cells of the immune system, these proteins are designed to bind invading organisms such as bacteria and viruses, leading to their destruction. Immunoglobulin G (IgG) is the most prominent form.

MP Bio NZ Immunoglobulin G is a high purity, lyophilized powder, captured with a high specificity from pooled bovine plasma using a full chromatographic method. The technology gently extracts the IgG, maintaining the native configuration throughout the process.


Applications of IgG:

  • Blocking reagent in immunoassays – ELISA, Western blotting, immune-diffusion

  • Reference antigen or standard

  • For conjugation of molecules requiring highly purified immunoglobulin

  • Used in the manufacture of diagnostic kits
