One fundamental and essential question in proteomics is the quantitation of proteins at very low concentrations or in complex protein mixtures. With increasing customer needs for specificity, accuracy and sensitivity a quantitation technique using stable isotope (13C / 15N) labelled internal peptide standards has been developed.
HeavyPeptide AQUA kits are the first kits that offer a complete solution both for absolute and relative quantitation of proteins by Mass Spectrometry (MS).
