Химические свойства
White/clear crystalline powder
Использование
Good's buffers Tricine is used as an electrophoresis buffer and involved in the separation of low molecular weight proteins and peptides. It operates in the pH range between 7.4 and 8.8. It acts as an effective scavenger of hydroxyl radicals during the study of radiation-induced membrane damage. It is also used in resuspension of cell pellets. It is a zwitterionic amino acid commonly useful in the pH range of 7.4-8.8 and the pKa is 8.05 at 25°C. This buffer is also used as an eluent in asymmetrical flow field-flow fractionation (AFFFF).
Общее описание
Tricine and its salts are used as biological buffers to control the pH of body fluids in vitro and in vivo. It acts as a precursor for polymers, oxazolones (with carboxylic acids), and oxazolidines (with aldehydes). Trizma can serve as an alkalizing agent in treating acidosis of the blood.
Биологическая активность
Electrophoresis buffer. Working pH range: 7.4 - 8.8. Commonly used in SDS-PAGE to seperate peptides. Also used in other electrophoresis methods, high performance liquid chromatography and ion exchange chromatopgraphy.
