2,4-dichlorophenoxyacetic acid/klh

2,4-D-KLH is a hapten-carrier protein conjugate formed by coupling 2,4-D to keyhole limpet hemocyanin (KLH). As a hapten, 2,4-D alone cannot induce an immune response and must be conjugated to a large molecular protein to become a complete antigen with immunogenicity. 2,4-D-KLH may be supplied as a lyophilized powder or as a solution. The solution is prepared in 0.01 M PBS (pH 7.4) buffer at a typical concentration of 1 mg/mL.
