Service Details
With the successive listing of antibody drugs, accurate sequence determination and structural characterization of antibodies have become more and more important in the process of drug development. The need for complete characterization of the quality attributes of these antibodies requires sophisticated techniques. Mass spectrometry (MS) has become an important analytical tool for the structural characterization of therapeutic antibodies, due to its superior resolution over other analytical techniques. It has been widely used in virtually all phases of antibody development. Structural features determined by MS include amino acid sequence, disulfide linkages, and many different post-translational, in-process, and in-storage modifications.

Creative Proteomics' deep antibody research knowledge reserve and skilled R&D team, after years of development, have built a complete antibody sequencing platform and applied mature sequencing technology to provide customers with one-stop antibody sequencing services. The new generation antibody sequencing platform to achieve fast and accurate analysis of antibody primary structure, so as to ensure that the every accuracy of antibody sequencing by using high-quality mass spectrometry platform and full-featured antibody sequencing data processing software, combined with bioinformatics database. This platform is suitable for sequence analysis of different subtypes of antibodies (IgG and IgM) and different types of antibodies (fluorescence-conjugated antibodies, immobilized antibodies, antibodies of different species).
