Bovine Oncostatin M (OSM) 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 OSM. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to OSM. 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 OSM, 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 OSM 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
Growth regulator. Inhibits the proliferation of a number of tumor cell lines. It regulates cytokine production, including IL-6, G-CSF and GM-CSF from endothelial cells. Uses both type I OSM receptor (heterodimers composed of LIFR and IL6ST) and type II OSM receptor (heterodimers composed of OSMR and IL6ST) (By similarity). Involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration (By similarity).

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level OSM were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 15.8pg/mL. |
ASSAY RANGE | 62.5-4000pg/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of OSM. No significant cross-reactivity or interference between OSM and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between OSM and all analogs, therefore, cross reactivity may still exist. |
