10% neutral buffered formalin fixes the tissue by cross-linking proteins that may cause a conformational change or “masking” of the antigenic epitope leading to reduced or absent antibody reactivity. The BD Retrievagen Antigen Retrieval Systems are designed to unmask the epitope and cause the enhancement of antibody staining.

  • Retrievagen A (pH 6.0) is provided as two separate solutions that need to be mixed
  • Retrievagen B (pH 9.5) is provided as a ready-to-use solution
