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

Cool pack

1-(2-Aminoethyl)-1H-pyrazol-4-ylphosphonic acid linker-BSA is a hapten-carrier protein conjugate formed by coupling 1-(2-Aminoethyl)-1H-pyrazol-4-ylphosphonic acid linker to bovine serum albumin (BSA). As a hapten, 1-(2-Aminoethyl)-1H-pyrazol-4-ylphosphonic acid linker 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 linker-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.
