Service Description

N and C terminal sequences are important structures and functional parts of protein and polypeptide, and they may play decisive roles in the biological function of protein. The main methods for protein C terminal sequencing include carboxypeptidase, chemical and tandem mass spectrometry, and the common methods for N terminal sequencing include Edman degradation sequencing and mass spectrometry. Each of these methods has the respective advantage and shortcoming. Therefore, the combination of a variety of different sequencing methods can adapt to the requirements of multiple protein sequencing. For example, Edman degradation may not well solve the problem of blockage and protein modification on the N terminal end. This drawback can be overcomed by mass spectrometry analysis. MtoZ Biolabs uses both Edman degradation system and MALDI TOF for N or C sequencing of biopharmaceutical products.
