Introduction and preparation method of biological buffer BICINE

Label: BICINE, preparation
Introduction: Buffer is a solution that can resist pH changes when a small amount of acid or alkali and water are added. PH buffer system plays an important role in maintaining the normal pH value of organisms and the normal physiological environment. Most cells can only work at a narrow pH Activities are carried out within the scope, and a buffer system is required to resist pH changes during the metabolic process. There are three main pH buffer systems in organisms, which are protein and bicarbonate buffer systems. Each buffer system accounts for The amount of is different in various types of cells and organs.

Basic Information

In biochemical research work, buffer solutions are often used to maintain the pH of the experimental system. Changes in the pH value of the solution system for research work often directly affect the effectiveness of our work. If the pH value of the extraction enzyme experimental system changes or changes too much , It will reduce the enzyme activity or even completely inactivate. So we have to learn to prepare buffer.
Bicine is one of the commonly used biological buffers. It is an amphoteric amino acid buffer and is active in the pH range of 7.6-9.0 (pKa of 8.3 at 25°C). Recommended buffer for low temperature biochemical work. Bicaine is used to prepare a stable serum guanosine enzyme substrate solution. A method for protein separation using dihydropyridine in thin-layer ion exchange chromatography has been published. Dihydropyridine has been used for peptide and protein crystallization.
