NEW YORK (GenomeWeb) – Cambridge Isotope Laboratories and MRM Proteomics said yesterday that they have signed an exclusive global supply agreement for mass spec-based targeted proteomics assays.

Under the agreement, CIL will have exclusive selling rights to MRM Proteomics' PeptiQuant kits used for quantitative proteomics and will provide distribution for the products worldwide.

The most widely used mass spec approach for targeted protein quantitation, MRM-MS assays typically incorporate stable isotope labeled (SIL) peptides to improve their accuracy and reproducibility.
