Making Molecules Fly: Ionization Methods in Mass Spectrometry

Mass spectrometry molecular separation via mass/charge (m/z) ratios. Each of the various ionization approaches excels in targeting different molecule types. Understanding these techniques can help you pick the optimal ionization method to “make your molecules fly” and reveal their unique mass spectra. Read this article to learn more.

Proteomics and Good Mass Spectrometry Data

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…

Learn-omics! What is that “Omics” I keep Stumbling Upon?

Learn-omics! What is that “Omics” I keep Stumbling Upon?

Genomics, transcriptomics, proteomics, metabolomics – words that in 2015 sound very familiar even to a freshman in any biology field. Although most have heard those words before, I keep encountering students or even post-graduates who find it difficult to explain what they are. So, to make things easier here is a peek behind the curtains…
