IdeZ Protease (IgG-specific)
Product Introduction
IdeZ Protease (IgG-specific) is a recombinant antibody specific protease that recognizes all human, sheep, monkey, and rabbit IgG subclasses, cleaving specifically at a single recognition site below the hinge region, to yield a homogenous pool of F(ab´)2 and Fc fragments. IdeZ Protease more effectively cleaves murine IgG2a than IdeS.
- Complete fragmentation of antibodies and immunoglobulin fusion proteins in 30 minutes under native conditions
- Supplied in solution; optimal activity and stability for up to 24 months
- Combine with PNGase F for complete fragmentation and deglycosylation
- Recombinant enzyme with no detectable non-specific protease contaminating activities
- Glycerol-free for optimal performance in HPLC and mass spectrometry analysis
- ≥95% purity, as determined by SDS-PAGE and intact ESI-MS

- IdeZ Protease efficiently cleaves human, humanized, chimeric, sheep,rabbit and monkey IgG as well as mouse IgG2a and IgG3. IdeZ Proteasewill also cleave Fc-fusion proteins, such as Enbrel.
- IdeZ Protease does not cleave mouse IgG1 or IgG2b, rat, porcine, bovineor goat IgG. It also does not cleave non-IgG isotypes including IgA,IgM, IgD and IgE.
