Merck, T5816-1KG, Tricine

Tricine is a zwitterionic biological buffer commonly used in enzyme assays, electrophoresis, and cell culture research. It has a higher negative charge compared to glycine, which enables it to migrate more rapidly. Tricine′s high ionic strength has the ability to cause more ion movement and less protein movement, resulting in the separation of low molecular weight proteins in lower percent acrylamide gels. It has been observed that Tricine is efficient in the separation of proteins ranging from 1 to 100 kDa through electrophoresis. According to a study, the 25 mmol/L Tricine buffer proved to be the most effective among ten other buffers tested for ATP assays using firefly luciferase. Further, Tricine is also used in capillary zone electrophoresis, high performance liquid chromatography and ion exchange chromatography.
