Biological Activity

Species: Human
Expression system: E.coli
Purity: > 90% as determined by SDS-PAGE
Predicted molecular weight: 25.81 kDa
Storage and stability: Use manual defrosting freezers to avoid repeated freeze-thaw cycles. Store at 2-8 °C for one week. Store at -20 to -80°C for 12 months from the date of receipt.



Biological activity: Mercaptan protease is involved in bone resorption in osteoclasts and may be partially involved in bone remodeling disorders. Showed strong protease activity against fibrinogen at acidic ph. It may play an important role in the degradation of extracellular matrix. Involved in the release of the thyroid hormone thyroxine (T4) through limited TG/ thyroglobulin proteolysis in the thyroid follicular lumen

Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human B2M Protein (Mammalian, C-6His)

β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states.

Recombinant Mouse E-Selectin/CD62E Protein (HEK293)

E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis.

Recombinant Human DPP4/CD26 (Mammalian, C-6His)

DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.

Recombinant Human USP14 (E.coli, N-6His)

USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1.
