Introduction
Human Ubquitin Conjugating Enzyme 9 (Ubc9) is a member of the E2 family and is specific for the conjugation of SUMO to a variety of target proteins. SUMO conjugation to target proteins is mediated by a different, but analogous, pathway to ubiquitinylation. This E2 is unusual in that it interacts directly with protein substrates that are modified by sumolyation, and may play a role in substrate recognition. Ubc9 can mediate the conjugation of SUMO-1 to a variety of proteins including RanGAP1, I?B?, and PML without the requirement of an E3 ligase.
Description
Ubiquitin-Conjugating Enzyme E2I Human Recombinant produced in E.coli is a 19.5 kDa protein containing 171 amino acids.
The UBE2I protein contains 6xHis tag and is purified by proprietary chromatographic techniques.

Source
Escherichia Coli.
Physical Appearance
Sterile Filtered white lyophilized powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in 1X PBS and 1mM DTT, pH 7.5.
Solubility
It is recommended to reconstitute the lyophilized UBE2I in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized UBE2I although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution UBE2I 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 carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
