Furazolidone /BSA is the antigen-adjuvant conjugate of Furazolidone and bovine serum albumin (BSA). By conjugating the antigen with the protein adjuvant , the production of antigen-specific antibodies in vaccine models can be enhanced. The conjugate does not affect protein folding or disrupt the major epitopes, and it can enhance cross-presentation and the generation of antigen-specific T cells.
