IdeZ Protease secreted by the Streptococcus equi
subspecies zooepidemicus. This product is an engineered recombinant protease
over expressed in Escherichia coli. It can specifically identify IgG, and
perform enzyme digestion at specific sites in the hinge region of the antibody,
and produce F(ab')2 fragments and Fc fragments, which can identify human and other
animal IgG, such as mouse, rabbit, monkey, sheep and human animal chimeric IgG,
etc, It can be used for structural characterization analysis of antibodies and
fusion protein drugs.
1. Add the desired amount of 5mg IgG in digestion buffer or other compatible buffer*.
2. Add IdeZ Protease (Tag Free)-1 to the reaction system:
• Add 1 unit of IdeZ Protease (Tag Free)-1 per 1µg of IgG to be digested.
• For example, add 5µl (200 units) of reconstituted IdeZ to digest 200µg of IgG.
3. Incubate sample at 37°C for 30–60 minutes
Please avoid repeated freeze-thaw cycles.
2μg (R: reducing condition, N: non-reducing condition).
