UCHL5 is a member of the peptidase C12 family. UCHL5 protein is a protease that specifically cleaves 'Lys-48'-linked polyubiquitin chains, and deubiquitinating enzyme related to the 19S regulatory subunit of the 26S proteasome.

Description: UCHL5 produced in E.Coli is a single, non-glycosylated polypeptide chain containing349 amino acids (1-329a.a.) and having a molecular mass of 39.7kDa.
UCHL5 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Physical Appearance: Sterile Filtered clear solution.

Formulation: The UCHL5 protein solution (0.5mg/ml) is formulated in 20mM Tris-HCl buffer (pH8.0), 5mM DTT, 200mM NaCl, 0.1mM PMSF, 2mM EDTA and 30% glycerol.

Biological Activity: Specific activity: > 500 pmole/min/ug. Measured by the hydrolysis of Ubiquitin-AMC at  pH 8.0, at 37°C.

Stability: Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.  For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
