Cluster of Differentiation 200 (CD200) ELISA Kit for Mouse

Intended Uses: This CHEMOKINE 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 ofCHEMOKINE in the sample, thisCHEMOKINE 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 versusCHEMOKINE concentration. The concentration ofCHEMOKINE in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Principle of the Assay: This CHEMOKINE 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 forCHEMOKINE. Standards or samples are then added to the microtiter plate wells andCHEMOKINE if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount ofCHEMOKINE present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific forCHEMOKINE are added to each well to "sandwich" theCHEMOKINE 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 containCHEMOKINE 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 CD200 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.

MBS729802 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Cluster of Differentiation 200 (CD200) 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 CD200. The ELISA analytical biochemical technique of the MBS729802 kit is based on CD200 antibody-CD200 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect CD200 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, CD200. 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(%).
