Bicine is a zwitterionic amino acid buffer, active in the pH 7.6-9.0 range (pKa of 8.26 at 25°C). Recommended buffer for low temperature biochemical work. Bicine is used for the preparation of stable substrate solution for serum guanase determination. The use of bicine in a thin layer ion exchange chromatography method for protein resolution has been published. Bicine has been utilized in peptide and protein crystallization. A kinetic study of a quaternary transition-state analogue complex of creatine kinase used bicine in the reaction buffer. A multiphasic buffer system for SDS-PAGE of proteins and peptides that incorporates bicine has been described. Recommended buffer for low temperature biochemical work.Used in the preparation of stable substrate solution for serum guanase determination.Spacer in plasma protein fractionation with Sephadex? by isotachophoresis.
