Ubiquitin Conjugating Enzyme E2B Human Recombinant ( UBE2B Human )

Data sheet

Formulation

Lyophilized from a 0.2m filtered concentrated (1 mg/ml) solution in 1X PBS and 1mM DTT, pH 7.5.

Solubility

It is recommended to reconstitute the lyophilized UBE2B in sterile water not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Ubiquitin Conjugating Enzyme E2B Human Recombinant produced in E.coli is a 19 kDa protein containing 166 amino acids.The UE2B protein contains 6xHis tag and is purified by proprietary chromatographic techniques.

Protein Background

This E2 enzyme encodes for the human homolog of the yeast DNA repair gene RAD6, which is induced by DNA damaging agents. UBE2B can conjugate ubiquitin to histone H2A in an E3- independent manner in vitro, and is essential for the multi-ubiquitination and

Expression host

Escherichia Coli.

Synonyms

Ubiquitin-conjugating enzyme E2 B, EC 6.3.2.19, Ubiquitin-protein ligase B, Ubiquitin carrier protein B, HR6B, hHR6B, E2-17 kDa UBC2, HHR6B, RAD6B, E2-17kDa, UBE2B.

Reagent Appearance

Sterile Filtered white lyophilized powder.

Stability

Lyophilized UBE2B although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution UBE2B should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a
