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

1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid-OVA is a conjugate of 1- (2-Aminoethyl) -1H-pyrazol-4-ylphosphonic acid and ovalbumin (OVA) . By conjugating the antigen with a protein adjuvant, the production of antigen-specific antibodies in vaccine models can be enhanced. The conjugate does not affect protein folding or disrupt major epitopes, and it can enhance cross-presentation and the production of antigen-specific T cells.
