Introduction
DeCyder™ MS Differential Analysis Software (DeCyder MS) is a new tool for visualization, detection, identification and label-free relative quantification of LC-MS and LC-MS/MS data. To Assess its quantification abilities, in a complex background, total soluble trypsin digested proteins extracts from strains of E.coli expressing varying levels of dihydrofolate reducatase (DHFR) were analysed using nanoLC-MS/MS. Full scan MS spectra were matched and quantified using DeCyder MS. A second experiment was performed on a bacterial strain containing an inducible integrase.This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License

Despite the developments in conventional PCR, the complexity of multiplex Real Time PCR is still limited due to the lack of sufficient detection channels. To achieve high-end multiplexing capacity on standard Real Time PCR machines, Anapa Biotech has developed the MeltPlex® technology (see box on right).
