Antibody-binding protein specificity for Protein A, Protein G, and Protein A/G which demonstrate binding specificity to IgG immunoglobulin through an interaction in the Fc region of the heavy chain domain. Protein A and G each show some preferences to certain types of antibody subclasses, and proper reagent selection may be required, Protein A/G offers the widest range of antibody subclass binding. Another immunoglobulin binding protein is Protein L which binds to the kappa light chain of the F(ab’)2 region.

Protein A Purification Description

Background
Protein A is 56 kDa protein molecule found in the cell wall of the bacterium Staphylococcus aureus. Protein A binds to immunoglobulins through interaction with the IgG heavy chain within the Fc region. Protein A does not bind to all IgG's equivalently and binding varies among species. Even within a species, Protein A interacts with some subclasses of IgG and not others. Protein A is well suited for purification of most rabbit, mouse, rat, and certain human IgG class of immunoglobulin. Rockland offers Protein G or recombinant Protein A/G when recommended by Rockland for optimal purifcation.
Application Note
Protein A purification is a process for isolating the IgG type of immunoglobulin protein from a complex mixture. The starting material is usually but not limited to polyclonal antisera, tissue culture supernatant, or ascites fluid. Typically protein A purification is performed when IgG enrichment is desired, and is often used to purify IgG prior to conjugation to a reporter molecule. The IgG is bound to an immobilized Protein A matrix, non-IgG impurities are wased away, lastly the IgG fraction is eluted and recovered. Rockland's Protein A purification process is ideal to recover a highly active IgG fraction from complex starting material.
Purity/Specifity
Chromatography is performed on up to 100 mL of antiserum, ascites or concentrated tissue culture supernatant to purify immunoglobulins known to bind (including certain mouse subclasses) Protein A.
