The two major direct methods of protein N-terminal sequencing are Edman degradation and mass spectrometry. Although the traditional Edman technique is very robust and provides de novo capabilities, the method suffers from several limitations, namely throughput, sensitivity, cost, and the need for ...
The preparation of protein samples for mass spectrometry and N-terminal sequencing is a key step in successfully identifying proteins. Mass spectrometry is a very sensitive technique, and as such, samples must be prepared carefully since they can be subject to contamination of the sample (e.g.,...
