Furazolidone/BSA is an antigen-adjuvant conjugate consisting of Furazolidone conjugated with bovine serum albumin (BSA). Conjugating the antigen to a protein adjuvant boosts the production of antigen-specific antibodies in vaccine models. The conjugate does not alter protein folding or disrupt major epitopes, while enhancing cross-presentation and the generation of antigen-specific T cells.
