We describe a fast and informative method to investigate the posttranslational modifications of monoclonal antibodies (MAbs). The MAb is first digested by a specific enzyme that cleaves heavy chains under the hinge domain. After reduction of disulfide bridges, three polypeptide

The immunoglobulin degrading enzyme of Streptococcus pyogenes, IdeS, is an unusual cysteine protease produced by group A streptococci for which the only known substrate is immunoglobulin G (IgG). To date, IdeS has not been found to cleave any of the

Host innate immune responses to DNA viruses involve members of the nucleotide-binding domain, leucine-rich repeat and pyrin domain containing protein (NLRP) family, which form "inflammasomes" that activate caspase-1, resulting in proteolytic activation of cytokines interleukin (IL)-1β and IL-18. We hypothesized

A comparative in vitro survey of physiologically relevant human and microbial proteinases defined a number of enzymes that induced specific hinge domain cleavage in human IgG1. Several of these proteinases have been associated with tumor growth, inflammation, and infection. A

Immunoglobulin G (IgG) antibodies are symmetrical molecules that may be regarded as covalent dimers of 2 half-molecules, each consisting of a light chain and a heavy chain. Human IgG4 is an unusually dynamic antibody, with half-molecule exchange ("Fab-arm exchange") resulting
