Bovine Tumor Necrosis Factor Beta (TNFb) 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 TNFb. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to TNFb. 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 TNFb, 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 TNFb 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
Cytokine that in its homotrimeric form binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR and TNFRSF14/HVEM (By similarity). In its heterotrimeric form with LTB binds to TNFRSF3/LTBR. Lymphotoxin is produced by lymphocytes and is cytotoxic for a wide range of tumor cells in vitro and in vivo.

Performance Characteristics
| REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level TNFb were tested 20 times on one plate, respectively. |
| SENSITIVITY | The minimum detectable dose was 0.041ng/mL. |
| ASSAY RANGE | 0.156-10ng/mL |
| SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of TNFb. No significant cross-reactivity or interference between TNFb and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between TNFb and all analogs, therefore, cross reactivity may still exist. |
