WebFAQ. Citrate buffer is used in Heat Induced Epitope Retrieval (HIER) methods. HIER is used to reverse the loss of antigenicity that occurs with some epitopes in formalin-fixed paraffin embedded tissues. During epitope retrieval, tissue slides are immersed in a solution and heated (>95° C) by hot plate or other appropriate heat source such as a ... WebFurthermore, citric acid does not seem to be a good buffer even considering pKa values ranging from 3.1 to 5.4 (Fig. 1A). This is because the values of the three dissociation constants are too close to permit distinction of the three proton receptor phases. The titration curve for sodium citrate with HCl (Figure 1B) confirmed the observation ...
