Human Interleukin 35 (IL35) ELISA Kit
Due to the possibility of mismatching between antigens from other origin and antibodies used in our kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by our products.
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL35. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to IL35. 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 IL35, 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 IL35 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For use with: Serum, Plasma, Tissue homogenates, Cell lysates, Cell culture supernates, and Other biological fluids.
For Research Use Only. Not for use in diagnostic procedures.
Target Information
Associates with IL27 to form the IL-27 interleukin, a heterodimeric cytokine which functions in innate immunity. IL-27 has pro- and anti-inflammatory properties, that can regulate T-helper cell development, suppress T-cell proliferation, stimulate cytotoxic T-cell activity, induce isotype switching in B-cells, and that has diverse effects on innate immune cells. Among its target cells are CD4 T-helper cells which can differentiate in type 1 effector cells (TH1), type 2 effector cells (TH2) and IL17 producing helper T-cells (TH17). It drives rapid clonal expansion of naive but not memory CD4 T-cells. It also strongly synergizes with IL-12 to trigger interferon-gamma/IFN-gamma production of naive CD4 T-cells, binds to the cytokine receptor WSX-1/TCCR. Another important role of IL-27 is its antitumor activity as well as its antiangiogenic activity with activation of production of antiangiogenic chemokines.

Performance Characteristics
| REPEATABILITY | Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level IL35 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level IL35 were tested on 3 different plates, with 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12% |
| SENSITIVITY | The minimum detectable dose was 5.6pg/mL. |
| ASSAY RANGE | 15.6–1,000pg/mL |
| SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of IL35. No significant cross-reactivity or interference between IL35 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between IL35 and all analogs, therefore, cross reactivity may still exist. |
