2021-07-21 12:00 The molecular weight of protein is an important analytical parameter in biochemistry. It is necessary to determine the molecular weight of recombinant proteins and key subunits by a fast and accurate method. Accurate quality determination allows us to assess the correctness of the primary protein sequence, the presence of mutations and post-translational modifications, possible degradation, homogeneity, and the degree of isotope incorporation during labeling.
