Analysis Note

Protein determined by biuret.

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.

Other Notes

Since the assay of this enzyme seems to be sensitive to minor variables, packages are dispensed per mg protein rather than in units.
