Methods of Determining Protein Stability

Posted by The Protein Man on Sep 18, 2018 2:30:00 PM

The stability of proteins is crucial in many in vitro protein studies and is considered a major requirement in functional studies involving native and recombinant proteins. Thus, understanding protein stability and preserving the native conformation and normal functions of your protein of interest can be very helpful when working with your protein of interest.

The Advantages of Using Trypsin for Mass Spectrometry

Posted by The Protein Man on Sep 11, 2018 2:30:00 PM

In mass spectrometry-based proteomics, nothing comes close to trypsin in breaking down protein mixtures into peptide fragments.  In fact, protein researchers consider trypsin as the runaway winner when it comes to protease activity and specificity – and there are a lot of good reasons why they do.
