A Prominent Supplier of Animal and Human Gamma Globulin

Gamma globulins, Ig’s for short, are a class of proteins found in the blood of humans and animals. The gamma identification refers to a specific range of positions after serum protein electrophoresis. Human antibodies that protect against viral and bacterial infectious diseases are an example of gamma globulins, although not all gamma globulins are antibodies.


Here at Pel-Freez Biologicals, we supply both human and animal gamma globulins, including goat gamma globulins, for research purposes. All of our products are designed in collaboration with some of the world’s leading universities, and undergo extensive laboratory tests to ensure that they can be safely used.

Supplying IGM Depleted Human Serum, IGG Depleted Plasma, and Negative Matrix Serum

Defined as the liquid component found in blood, serum is comprised of electrolytes, immunoglobulin, and proteins. The product is typically used for selectively removing contaminant antibodies that are immobilized on a solid matrix. Human serum can also be utilized in anti-PA (anti-protective antigen) IgG measurements which use PA-coupled microspheres.


IgM/IgG/IgA depleted human serum can also serve as a control serum in enzyme-linked immunosorbent assay, immunoelectrophoresis, and immunodiffusion. Moreover, it can also be used as:

  • Micro neutralization assay
  • SRH (single-radial hemolysis) repeatability assay
  • Control sera for assessing neuraminidase inhibition
