Prostaglandin 1 Synthase (PTGIS) ELISA Kit for Human

For samples: Serum, plasma, cell culture supernatants, body fluid and tissue homogenate

INTENDED USE This PTGIS ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human PTGIS. This ELISA kit for research use only!

PRINCIPLE OF THE ASSAYPTGIS ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-PTGIS antibody and an PTGIS-HRP conjugate. The assay sample and buffer are incubated together with PTGIS-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the PTGIS concentration since PTGIS from samples and PTGIS-HRP conjugate compete for the anti-PTGIS antibody binding site. Since the number of sites is limited, as more sites are occupied by PTGIS from the sample, fewer sites are left to bind PTGIS-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PTGIS concentration in each sample is interpolated from this standard curve

Small volumes of PTGIS elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS721938 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Prostaglandin I Synthase (PTGIS) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing PTGIS. The ELISA analytical biochemical technique of the MBS721938 kit is based on PTGIS antibody-PTGIS antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect PTGIS antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, PTGIS. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
