Ubiquitin Conjugating Enzyme E2B Human Recombinant

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 degradation of N-end rule substrates. Additionally, UBE2B may have a role in sepsis-induced muscle protein proteolysis and cancer-induced cachexia.
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.

Purity >96% as determined by SDS-PAGE and HPLC
Formulation Sterile Filtered white lyophilized powder.
Lyophilized from a 0.2μm filtered concentrated (1 mg/ml) solution in 1X PBS and 1mM DTT, pH 7.5.
Stability The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Solubility It is recommended to reconstitute the lyophilized UBE2B in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Usage LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
