Storage Duration: 3 years

Description:

Protein L, derived from Peptostreptococcus magnus, is a protein that can bind to a wide range of immunoglobulins. It can only bind to the antibody's kappa light chain without affecting the antibody's antigen binding site. Compared with protein A or protein G, protein L can bind antibodies from various sources and subclasses more widely. It does not bind immunoglobulins from cattle, goats or sheep, and can be used to purify monoclonal antibodies from culture medium supplemented with BSA or FCS.
