Intact mass analysis of peptides, proteins and antibodies are a strong evidence for correct expression of specific proteins. It is also a fast analysis to verify the purity, analysis of post-translation modifications and eventual degradation products.

Our Top-of-the-line mass spectrometry instruments provide very accurate weight of both proteins and antibodies. We can perform the analysis on a few µg of protein. The analysis is very sensitive and we determine the weight with an accuracy within 10 ppm (+/- 1 Da for a 100 kDa protein).

The molecular weight analysis can be conducted before and after reduction. You can also use it before and after de-glycosylation, and even after specific digest forming sub-units.
