WebFor example, if you prepare a Tris buffer at pH 7.0 at 4.0°C and perform a reaction in that same buffer at 37°C, the pH will drop to 5.95. If you have a Tris buffer prepared at 20°C with a pKa of 8.3, it would be an effective buffer for many biochemical reactions (pH 7.3–9.3), but the same Tris buffer used at 4°C becomes a poor buffer at ... 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 … 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 ... earth tea brewer
