Intoduction
to E2/UBCE
|
Ubiquitin-conjugating enzymes are known as E2 enzymes. They perform the second step of ubiquitination. The E2 enzyme receives activated ubiquitin from E1, conjugates it, then binds to E3 where it is transferred to a lysine residue on the targeted protein. The overall ubiquitination reaction causes protein degradation by proteasomes.
Ubiquitin conjugating enyme is located in the cytosol. To isolate fractions for ELISA assay, use a non-denaturing detergent lysis buffer such as Part No. ELSP-1, or similar to lyze membranes and release a soluble cytosolic fraction. The protocol associated with Part No ELSP-1 can be used to isolate cytosolic fractions for ELISA measurement.

Methods
Overview
|
The included ELISA micro-strip plate is provided pre-coated with an a monoclonal capture antibody selective to the antigen. Samples are pre-mixed with a biotin-linked detection antibody and streptavidin-HRP, which are then added to the plate. The plate is washed after a 60 min incubation period. Color reagents are added, resulting in a reaction with HRP that yields a blue colored solution. A stop solution is applied to terminate the reaction, and the solution is measured at 450nm.
