SPS TMT Method Development- What is New on Lumos
Multiplexing On the Benchtop Orbitrap System (Q Exactive Series)
?Take advantage of segmented quadrupole (QE Plus and HF), for more efficient isolation in narrow windows
?Suited for the analysis of low and medium complexity samples
?Pre-fractionation recommended for high complexity samples to improve quantification accuracy and precision (Pierce Spin Column)
Data Analysis
Proteome Discoverer 2.1
?New method TMT quantification
?TMT correction factors (for all TMT reagents) with new user interface
?Use of “Razor” peptides for protein quantification
?Modified form of Gygi group’s S/N-based approach to TMT quantification
?Custom ratio generation
?New heat map-like coloring of ratios and scaled abundances
Note that almost of all these changes are also applied to isotope-labeled quantification (e.g. SILAC)
