Sodium Citrate Buffer (0.5M, pH 5.5)

Description: Sodium Citrate Buffer, 0.5M, pH 5.5 is a commonly used buffer solution primarily composed of citric acid and disodium hydrogen phosphate (Na2HPO4). It is utilized in heat-induced epitope retrieval (HIER) to reverse the loss of antigenicity in epitopes within formalin-fixed, paraffin-embedded tissues. This buffer is the preferred solution for most antibodies.
