Synonym: N-[Tris(hydroxymethyl)methyl]glycine

Tricine is a zwitterionic amino acid. It is an organic derivative of tris and glycine used in buffer solutions. Tricine has been recommended as the buffer of choice in SDS-PAGE systems, in separating proteins in the range of 1 to 100 kDa1. Tricine is also an effective hydroxyl radical scavenger used to protect molecules during radical generating procedures such as irradiation2.
Useful pH Range 7.4 - 8.8
Working concentration range 50mM3
