Heat Shock Protein 90 (HSP 90) ELISA Kit for Human

Principle of the assay: HSP-90 ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for HSP-90. Standards or samples are then added to the microtiter plate wells and HSP-90 if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of HSP-90 present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for HSP-90 are added to each well to "sandwich" the HSP-90 immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain HSP-90 and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The HSP-90 concentration in each sample is interpolated from this standard curve.

Small volumes of HSP 90 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.

MBS729618 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Heat Shock Protein 90 (HSP 90) 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 HSP 90. The ELISA analytical biochemical technique of the MBS729618 kit is based on HSP 90 antibody-HSP 90 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect HSP 90 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, HSP 90. 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(%).
