InvivoGen provides several methods for the purification of monoclonal IgA or IgG antibodies. The correct choice of purification method depends on the immunoglobulin class, the source of the antibody (e.g., serum or cell culture supernatant), the species in which it was raised and the intended use of the antibody.
- Peptide M for IgA purification
- Protein L for IgG and IgA purification
- Protein G for IgG purification
