Anwendungen & Verwendung
Beschreibung
Bicine is an amino acid that results from amine degradation due to the presence of oxygen and/or sulfur dioxide. The amine solvents that undergo this degradation are MDEA, DEA, TEA, and mixed amine solvents containing any of these amines. As a zwitterionic amino acid buffer agent, bicine is active in the pH 7.6-9.0 range (pKa of 8.26 at 25°C). Bicine is a recommended buffer for low-temperature biochemical work. It is used for the preparation of stable substrate solution for serum guanase determination. It can be used as a nitrogenous strength enhancer to regulate cement hydration and improve cement properties. Studies have found that bicine significantly changes the morphology of portlandite crystals from a parallel-stacked lamellar shape to a distorted one and also decreases the pore size of the hardened cement paste at an early age[1]. In particular, bicine could promote the rapid formation of β-sheet-rich amyloid-β fibrils[2].
Verwenden
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.
