Application

Triosephosphate isomerase has been used in a study to assess differential expression of fourteen proteins of uveal melanoma. Triosephosphate isomerase has also been used in a study to investigate the use of sigmoid pH gradients in free-flow isoelectric focusing of human endothelial cell proteins.

Physical form

Crystalline suspension in 2.7 M (NH4)2SO4, 0.5 mM EDTA, pH 6.5

Analysis Note

Protein determined by biuret.

Other Notes

One unit will convert 1.0 μmole D-glyceraldehyde 3-phosphate to dihydroxyacetone phosphate per min at pH 7.6 at 25 °C.
Since the assay of this enzyme seems to be sensitive to minor variables, packages are dispensed per mg protein rather than in units.

Prefractionation of proteins enhances the resolution of proteome analysis of whole cells. Free-flow electrophoresis (FFE) provides a useful step in various prefractionation protocols, since matrix-free isoelectric focusing (FF-IEF) performed in this machine enables the enrichment of large, easily absorbable, sensitive
