Proteasome Activator Subunit 2 Human Recombinant ( PSME2 Human )

Data sheet

Formulation

The PSME2 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.1M NaCl, 1mM DTT, 0.1mM PMSF and 20% glycerol.

Purity

Greater than 95% as determined by SDS-PAGE.

Description

PSME2 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 259 amino acids (1-239) and having a molecular mass of 29.5 kDa.PSME2 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromat

Protein Background

PSME2 is an IFN-gamma inducible proteasome activator essential for production of several key histocompatibility (MHC) class I antigens. Downregulation of PSME2 causes unusual proteasome activation and is connected to the development of intimal hyperplasia

Expression host

E.coli.

Synonyms

Proteasome (prosome, macropain) activator subunit 2 (PA28 beta), PA28beta, Activator of multicatalytic protease subunit 2, Proteasome activator 28 subunit beta, 11S regulator complex subunit beta, PA28B, REG-beta, cell migration-inducing protein 22, MCP a

Reagent Appearance

Sterile Filtered colorless solution.

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.
