Citrate Buffer is intended to be used for the heat induced epitope (or antigen) retrieval (HIER) of formalin-fixed, paraffin-embedded (FFPE) tissues prior to immunohistochemical (IHC) staining.

Citrate buffer solution breaks the cross-linking of proteins, thereby revealing the antigens and epitopes in the FFPE tissue section and enhancing the staining intensity of many antibodies. This product is a ready-to-use powder, and add distilled water to 1L before use to obtain a solution with pH 6.0.

Features:

1. Convenient—Dissolve contents of one envelope in water and the buffer is ready to use
2. Reduced preparation time — no reagents to weigh or filter
3. Quality-controlled reagent — guarantees reproducible results

Component：1. Citric acid—1.8mM
