Patent

CA 2457695

The invention provides reagents, kits and methods for detecting and/or quantifying proteins in complex mixtures, such as a cell lysate. The methods can be used in high throughput assays to profile cellular proteomes. In one aspect, the invention provides a peptide internal standard labeled with a stable isotope and corresponding in amino acid sequence to the amino acid sequence of a subsequence of a target polypeptide. In another aspect, the peptide internal standard is labeled at a modified amino acid residue and is used to determine the presence of, and/or quantitate the amound of a particular modified form of a protein.

La présente invention concerne des réactifs, des kits et des techniques de détection et/ou de quantification de protéines dans des mélanges de complexes, tels qu'un lysat cellulaire. On peut utiliser ces techniques dans des dosages à haut rendement pour profiler des protéomes cellulaires. Dans un de ses aspects, cette invention concerne une norme interne de peptide marquée avec un isotope stable et correspondant dans une séquence d'amino acide à la séquence d'amino acide d'une sous séquence d'un polypeptide cible. Dans un autre aspect de cette invention, la norme interne de peptide est marquée au niveau d'un résidu d'amino acide modifié et elle est utilisée pour déterminer la présence d'une forme modifiée particulière de protéine et/ou pour quantifier celle-ci.
