Tricine is a zwitterionic buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is part of the Tris family of buffers with a useful pH range of 7.4 – 8.8. Tricine is commonly used in SDS-PAGE to separate peptides that are in the molecular weight range of 1 to 100 kDa. It is also used in capillary zone electrophoresis, high performance liquid chromatography and ion exchange chromatography. Tricine was determined to be the best buffer tested for use in ATP assays involving firefly luciferase. Tricine can serve as scavenger of hydroxyl radicals; this should be taken into consideration if using tricine in the presence of an enzyme with oxidase activity. Tricine forms a complex with Cu(II). The addition of Cu2+ to a solution enables tricine to be used in the Lowry protein assay. Tricine can be used as a substitute for protocols that utilize the controlled substance barbital as a buffer.
