Product Description & Scientific Applications

Tricine (N-[tris(hydroxymethyl)methyl]glycine; N-tris(hydroxymethyl)methylglycine) is a zwitterionic aminopolyol amino-acid buffer of the Good's series, combining a glycine carboxylate and secondary amine with a tris(hydroxymethyl) headgroup. Its buffering pKa is 8.1 at 25 °C, with an effective range of pH 7.4–8.8, spanning the near-physiological to mildly alkaline window. It is water-soluble.

Buffer chemistry and temperature dependence. Tricine buffers through its secondary-amine group; the pKa falls as temperature rises, while ionic strength has little effect. It has also been characterised as an ampholyte pH-reference standard, determined alongside BES in dimethyl sulfoxide/water mixtures down to subzero temperatures.

Tricine-SDS-PAGE and protein electrophoresis. Tricine-SDS-PAGE separates proteins in the mass range 1–100 kDa and is the preferred electrophoretic system for resolving proteins smaller than 30 kDa. It uses lower acrylamide concentrations than other systems, which facilitates electroblotting — particularly important for hydrophobic proteins. Tricine also serves as a component of non-barbital agarose buffers for immuno- and zone electrophoresis.

Metal coordination. The tris(hydroxymethyl) nitrogen and the glycine carboxylate make tricine a metal chelator. In its copper(II) complex the tricine anion binds Cu2+ as a tridentate O,N,O′ ligand, giving a five-coordinate, approximately square-pyramidal metal centre within a chloride-bridged polymeric chain
