Complex Mixture ID Introduction Modern LC-MS/MS platforms can identify several thousands of proteins from a single sample. We realize that many different types of samples can be submitted for proteomics analsyis, so we accept a wide range of sample formats, including: On-bead (magnetic beads preferre…

Computing and Data Analysis Continuous improvement in mass-spectrometry instrumentation means that proteomics facilities are generating a growing amount of data, and tackling increasingly complex datasets. The rise of quantitative proteomics in particular demands robust data analysis techniques to en…

Cutting Gels Introduction Many proteomics samples are well suited for SDS-PAGE, including protein identification and PTM identification. We recognize that a gel approach may not be compatible with all samples, so please contact us if you have concerns about running your sample into a gel. We require …

Silac Quantitation Introduction Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) is a powerful technique for comparing protein (and peptide) amounts between two or three conditions. Developed in the lab of Matthias Mann it is one of the most widely used labeled quantitation methods in p…

TMT Quantitation Introduction Tandem Mass Tag (TMT) technology is a powerful technique for comparing protein (and peptide) amounts between six to eighteen conditions. This technique involves labeling samples after digestion, meaning this technique can be used on in vivo samples, unlike SILAC. TMT or …
