1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid-BSA

1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid-BSA is a hapten-carrier protein conjugate formed by coupling 1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid to bovine serum albumin (BSA) . As a hapten, 1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid alone cannot induce an immune response and must be conjugated to a large molecular protein to become a complete antigen with immunogenicity. 1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid-BSA may be supplied as a lyophilized powder or as a solution. The solution is prepared in 0.01?M TBS (pH 7.4) buffer at a typical concentration of 1?mg/mL.
