rProtein A Chromstar® FF is an affinity chromatography medium for antibody purification, which separates through the specific interaction between antigen and antibody. This chromatography medium is used for the purification of monoclonal and polyclonal antibodies.
Recombinant protein A is produced in E. coli and engineered with directional conjugation to enhance binding capacity: Epoxy-based conjugation ensures low ligand shedding. Recombinant protein A has similar specificity for the IgG Fc region as native protein A, allowing for increased selection and yield.
