Anti-Proteinase 3 Antibody IgG (PR3 ab-IgG) ELISA Kit for Rat

Intended Uses: This PR3 ab-lgG ELISA kit is intended Laboratory for research use only.The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of PR3 ab-lgG in the sample, this PR3 ab-lgG ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus PR3 ab-lgG concentration. The concentration of PR3 ab-lgG in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Principle of the Assay: This PR3 ab-lgG enzyme linked immunosorbent assay applies a technique called a quantitative sandwich immunoassay. The microtiter plate provided in this kit has been pre-coated with a monoclonal antibody specific for PR3 ab-lgG. Standards or samples are then added to the microtiter plate wells and PR3 ab-lgG if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of PR3 ab-lgG present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for PR3 ab-lgG are added to each well to "sandwich" the PR3 ab-lgG immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, A and B substrate solution is added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period.Only those wells that contain PR3 ab-lgG and enzyme-conjugated antibody will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the colour change is measured spectrophotometrically at a wavelength of 450 nm.

Small volumes of PR3 ab-IgG 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.

MBS732336 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Anti-proteinase 3 antibody IgG (PR3 ab-IgG) 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 PR3 ab-IgG. The ELISA analytical biochemical technique of the MBS732336 kit is based on PR3 ab-IgG antibody-PR3 ab-IgG antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect PR3 ab-IgG antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, PR3 ab-IgG. 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(%).
