| Quantitation by concatenated tryptic peptides (QCAT) |
|---|
| Method for absolute quantitation of a protein or proteins in a multiplexed fashion using isotope-labeled peptides as surrogate internal standards. The labeled peptides are produced by synthesizing a gene coding for all desired peptides, expressing this gene in E. coli culture containing appropriately labeled substrate, and digesting with trypsin the expressed protein composed of the desired concatenated peptides. |
