Formalin or other aldehyde fixation forms protein cross-links that mask the antigenic sites in tissue specimens, thereby giving weak or false negative staining for immunohistochemical detection of certain proteins. The citrate based solution is designed to break the protein cross-links, therefore unmask the antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, thus enhancing staining intensity of antibodies.

Features:

1. Citrate buffer antigen retrieval is used with paraffin embedded, formalin or paraformaldehyde-fixed tissues
2. Under elevated temperatures, citrate buffer has been shown to greatly improve detection of some proteins, although not all
