Proteomics and Good Mass Spectrometry Data

By Zach Poss | March 14, 2017

It is currently possible to analyze thousands of proteins in a single sample using mass spectrometry (MS) and a database of predicted protein sequences, referred to as ‘bottom-up’ proteomics. With this technology, you can measure protein levels and interactions. Also, you can examine changes in post-translational modifications (PTMs) and isoforms (in an unbiased manner). Working with…
