背景介绍

  • 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.

产品组分
操作步骤

  • 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

注意事项

  • Please avoid repeated freeze-thaw cycles.

酶活定义
  • One unit will cleave ≥95% of 1µg of recombinant monoclonal IgG in 30 minutes at 37°C

  • 电泳

    • 2μg (R: reducing condition, N: non-reducing condition).
