Global Protein G, L, and A Resin Market Research Report, Competitive, Technology and Forecast Analysis 2025-2032
Protein G, L, and A resins are specialized chromatography matrices used for the purification of proteins based on their interactions with specific binding domains. Protein G resin is derived from Streptococcus bacteria and exhibits high affinity for the Fc region of immunoglobulin G (IgG) antibodies, making it widely used for antibody purification. Protein L resin, on the other hand, is derived from bacterial sources and binds to a broader range of antibody classes, including IgG, IgM, and IgA, making it valuable for purifying antibodies with diverse structures. Protein A resin, derived from the bacterium Staphylococcus aureus, specifically binds to the Fc region of IgG antibodies from mammalian species, making it suitable for the purification of various antibodies. These resins are integral components in protein purification processes, enabling researchers to isolate and obtain highly pure antibodies and other proteins for a range of scientific and therapeutic applications.
