Ubiquitin-Conjugating Enzyme E2L 3 (UBE2L3) CLIA Kit: The microtiter plate provided in this kit has been pre-coated with an antigen. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated secondary antibody. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Ubiquitin Conjugating Enzyme E2L3 (UBE2L3) level in the sample or standard.
