| | Bicine Usage And Synthesis |
| Chemical Properties | White/clear crystalline powder | | Uses | To prepare stable substrate solution for the determination of guanine deaminase. The buffer is widely used with the working concentration of 3-100mM. | | Uses | Biological buffer and chelating agent. | | Uses | A zwitterionic amino acid buffer agent used for low temperature work. 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. | | Definition | ChEBI: N,N-bis(2-hydroxyethyl)glycine is a bicine that is a Good's buffer substance, pKa = 8.35 at 20 ℃. It is a conjugate acid of a [bis(2-hydroxyethyl)amino]acetate. It is a tautomer of a [bis(2-hydroxyethyl)ammonio]acetate. | | Purification Methods | Dissolve bicine in a small volume of hot water and precipitate it with EtOH, twice. Repeat once more but treat the aqueous solution with charcoal Purification of Biochemicals — Amino Acids and Peptides and filter before adding EtOH. Also crystallise it from concentrated aqueous solutions. [Torn & Kolthoff J Am Chem Soc 77 2061 1955, Chaberek et al. J Am Chem Soc 75 2185 1953, Beilstein 4 IV 2390.] |
