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

1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid linker/BSA is the conjugate of 1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid linker and bovine serum albumin (BSA) . By conjugating the antigen with a protein adjuvant, it enhances the production of antigen-specific antibodies in vaccine models. The conjugate does not affect protein folding or disrupt key epitopes, and it can enhance cross-presentation and the generation of antigen-specific T cells.
