Recombinant Human Proteasome (prosome, macropain) Inhibitor Subunit 1 (PI31), His-tagged

Cat. No.: PSMF1-1567H
Product Overview: Recombinant human PSMF1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
Description: PSMF1 is a protein that inhibits the activation of the proteasome by the 11S and 19S regulators. The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits.
Form: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 20% glycerol, 1mM DTT, 0.1mM PMSF.
Molecular Weight: 31.9 kDa (291aa), confirmed by MALDI-TOF.
Purity: >85% by SDS-PAGE
Concentration: 0.5 mg/ml (determined by Bradford assay)
