Enzymes & Kinases

Explore bioactive recombinant enzymes and kinases for signaling, proteolysis, and post-translational modification studies. Expressed in HEK293, CHO, or E. coli, each lot is activity-verified with specific units (U/mg or mU/µg) and documented assay conditions (substrate, pH, cofactors). Options include carrier-free, His-tag, and Fc-fusion formats with low endotoxin for sensitive cell-based workflows. RUO

Selection Guide

  1. Activity Readout: Confirm unit definition (U/mg), substrate & assay buffer; match to your platform (fluorescent/colorimetric/radio).
  2. Cofactors & Conditions: ATP/Mg2+/Mn2+, pH & temperature optima; check inhibitors/activators listed in the CoA.
  3. Expression System: HEK293/CHO for glycosylated enzymes and stability; E. coli for rapid screens.
  4. Endotoxin & Format: Choose low endotoxin and carrier-free for cell assays; select His/Fc tags per capture/purification needs.
  5. Specific Variants: WT vs. catalytic-dead/mutants for negative controls or mechanistic studies.

Applications

FAQs

How are enzyme “units” defined on your CoA?

Units reflect product formation or substrate turnover per time under stated conditions (substrate, buffer, pH, temperature, cofactors). Always replicate those conditions when comparing activity.

Which expression system should I choose?

Use HEK293/CHO for enzymes requiring glycosylation or complex folding; E. coli suits fast screens or tags not affecting function.

What endotoxin level is recommended for cell assays?

Typically ≤0.1 EU/µg. Verify the lot-specific CoA and include appropriate controls.
