4-Hydroxy-3-Nitrophenyl Acetate-BSA

4-Hydroxy-3-Nitrophenyl Acetate-BSA is a hapten-carrier protein conjugate formed by coupling 4-Hydroxy-3-Nitrophenyl Acetate (NP) to bovine serum albumin (BSA) . As a hapten, 4-Hydroxy-3-Nitrophenyl Acetate alone cannot induce an immune response and must be conjugated to a large molecular protein to become a complete antigen with immunogenicity.
