          Leading Partner For Peptides

          Heavy isotope-labeled peptide

          Stable Isotope Peptides for Quantitative Proteomics - Heavy Peptides

          Guoping pharmaceutical ---Your reliable partner in pharmaceutical R&D

          To date, quantitative protein analysis has mostly relied on antibody-based (e.g. ELISA) methods. Recent advances in the sensitivity and reliability ofLC-MS instrumentation are making mass spectrometry-based methods competitive for doing quantitative protein analysis. Additionally, LC-MS methods can be multiplexed so that hundreds to thousands of proteins can be quantified in a single assay, which is a huge advance for both discovery of biomarkers as well as clinical diagnostic assays. The gold standard for MS-based quantitative methods is to use a mass-shifted, stable-isotope-labeled peptide standard spiked into the sample of interest, which then allows quantification from a simple ratio of the labeled peak height to the unlabeled. This stable isotope dilution (SID) method is the basis for all selective reaction monitoring (SRM) and multiple reaction monitoring (MRM) method.

          Guoping pharmaceutical is please to offer isotope labeled peptides , the industry's first complete suite of peptide and antibody SIS products and services. A world leader in isotope labeled peptides since 2008, Guoping has the experience, knowledge, products and services to be your one-stop shop all peptide based quantitative proteomics needs.
