Affinity chromatography plays a major role in their production of antibodies and antibody-based products. The basis for antibody affinity chromatography is the high affinity and specificity of protein A and protein G for the Fc-region of IgG from a variety of species. 

Protein A and G immobilized on chromatography media and are highly effective in isolating subclasses of IgG from ascites fluid, cell culture supernatants, and serum. Protein A and protein G differ in their ability to bind antibodies of different species and subclasses, and are widely used for the routine purification of antibodies.

G-Biosciences Pearl Resin is also offered as a one-step purification of IgGs from serum.

Resins for IgM, IgY and IgA are also available.

G-Trap™ Protein G are prepacked ready to use columns for affinity purification of Immunoglobulins G. The column is packed with resin, which is covalently coupled to recombinant Protein G.   Recombinant Protein G is coupled covalently by proprietary coupling method to highly cro..

Immobilized protein G is for binding the constant domains of immunoglobulin (Ig) molecules (see Figure 1). It is ideal for the easy one-step purification of classes, subclasses and fragments of immunoglobulins for biological fluids and cell culture media. Protein G is a modified form of Streptococca..
