Merck, T5816-25G, Tricine

General description
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.
Application
Buffer component for separation of low molecular weight peptides.
Tricine serves as a versatile buffering agent suitable for separating low molecular weight proteins in lower percent acrylamide gels, has demonstrated efficacy in ATP assays employing firefly luciferase, and has shown potential in scavenging hydroxyl radicals during the investigation of radiation-induced membrane damage. Additionally, it has played a role in isolating and purifying ribosomes engaged in the translation of specific mRNA and containing specific peptidyl-tRNA molecules. Tricine has also been employed in the synthesis of RNA oligonucleotides and the fabrication of high-density DNA microarrays, enabling the exploration of mechanisms underlying nucleic acid·ligand interactions and library preparation through photolithography.
