Oncostatin M (OSM) BioAssay™ ELISA Kit (Rat)

For the quantitative determination of rat oncostatin M (OSM) in serum and plasma.

Sensitivity:
3.9pg/ml

Detection Range:
15.6-1000pg/ml

Specificity:
This assay has high sensitivity and excellent specificity for detection of rat OSM. No significant cross-reactivity or interference between rat OSM and analogues was observed.

Assay Principle:
This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for OSM has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any OSM present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for OSM is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of OSM bound in the initial step. The color development is stopped and the intensity of the color is measured.
