 IgM Purification Using LigaTrap's® IgM Purification Resin


About IgM

IgM monoclonal antibodies have become increasingly favorable for their use as therapeutic tools, while remaining popular for their research and diagnostic applications. Protein A and G chromatography continues to lead the life science industries for the purification of IgG, however Protein A/G proves unsuitable for IgM purification proves. In addition to increased yields and purity levels, LigaTrap® Human IgM Purification Resin (LT-143) address many of the shortfalls related to standard affinity ligands including challenges with proteolysis and repeated sanitization associated with other common purification methodologies.
