IgG-Digesting Enzymes for Therapeutic Antibody Characterization

IdeS and IdeZ Proteases are immunoglobulin G (IgG)-degrading enzymes that are valuable tools for the characterization of therapeutic antibodies, Fc fusion proteins and antibody-drug conjugates.

IdeS and IdeZ Proteases are fast and easy-to-use; complete digestion can be achieved in 30 minutes without optimization. Cleavage is highly reproducible and specific at a single site below the hinge region.

Both IdeS and IdeZ Proteases effectively cleave human IgG1, IgG2, IgG3 and IgG4, monkey, sheep, rabbit, humanized and chimeric IgGs as well as Fc-fusion proteins. However, only IdeZ Protease cleaves mouse IgG2a and IgG3.

Cleavage Specificity of IdeS and IdeZ Proteases

12335MB-W

IdeS and IdeZ Proteases are immunoglobulin G (IgG)-degrading proteases that cleave with high specificity.

IdeS Protease is derived from Streptococcus pyogenes. It is an engineered, recombinant protease overexpressed in E. coli. IdeS Protease cleaves IgG at a single site below the hinge region, yielding F(ab')2 and Fc fragments as shown here.

IdeZ Protease is derived from Streptococcus equi subspecies zooepidemicus. It is also an engineered, recombinant protease overexpressed in E. coli. Like IdeS, IdeZ Protease specifically cleaves IgG molecules below the hinge region, yielding F(ab')2 and Fc fragments. However, IdeZ Protease has significantly improved activity against mouse IgG2a and IgG3 subclasses compared to IdeS Protease.
