Protein A resin is a surface protein that occurs naturally in the cell wall of the bacteria Staphylococcus aureus. It is used in affinity chromatography owing to its ability to bind proteins such as antigens, immunoglobulins and others. The increasing demand for affinity chromatography, coupled with the rising number of procedures for separating biochemical mixtures, is the prime driver of the market. The growing demand for affinity chromatography procedures is a direct outcome of the growth of the biotechnology industry, particularly the development of antibodies, enzyme and protein-based therapies & drugs. Protein A resin is in high demand in the research and development sectors owing to the high intensity of affinity chromatography for the separation of antigens & antibodies, receptor & ligand or protein & nucleic acids during the course of research. Another driver of the protein A resin market is the key advantages of protein A resin-based affinity chromatography such as high selectivity, very rapid mass transport, superior capacity vs. flow rate, the separation of complex mixtures and the final highly purified product.
