Browse our collection of recombinant enzymes — including proteases, kinases, phosphatases, and metabolic enzymes. Each enzyme is produced with high purity and verified enzymatic activity, supporting applications in drug target screening, biochemical pathway analysis, and structural biology. Available in His-tagged and tag-free formats. All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

Verified Enzymatic Activity Each enzyme is functionally validated with specific activity data (U/mg) provided on the CoA. Substrate specificity and kinetic parameters documented where applicable.
Drug Screening Ready Suitable for high-throughput enzyme inhibition assays, IC₅₀ determination, and mechanism-of-action studies in drug discovery workflows.
Multiple Expression Systems Produced in E. coli for high yield or mammalian systems (HEK293/CHO) when post-translational modifications are required for native activity.
