Human Ubiquitin Conjugating Enzyme E2L3 (UBE2L3) ELISA Kit
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to UBE2L3. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to UBE2L3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain UBE2L3, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of UBE2L3 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Target Information
Ubiquitin-conjugating enzyme E2 that specifically acts with HECT-type and RBR family E3 ubiquitin-protein ligases. Does not function with most RING-containing E3 ubiquitin-protein ligases because it lacks intrinsic E3-independent reactivity with lysine: in contrast, it has activity with the RBR family E3 enzymes, such as PRKN and ARIH1, that function like RING-HECT hybrids. Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-11'-linked polyubiquitination. Involved in the selective degradation of short-lived and abnormal proteins. Down-regulated during the S-phase it is involved in progression through the cell cycle. Regulates nuclear hormone receptors transcriptional activity. May play a role in myelopoiesis.

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level UBE2L3 were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 0.072ng/mL. |
ASSAY RANGE | 0.156-10ng/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of UBE2L3. No significant cross-reactivity or interference between UBE2L3 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between UBE2L3 and all analogs, therefore, cross reactivity may still exist. |
