ECF (Eosinophil Chemotactic Factor) (ECF) ELISA Kit for Human

Principle of the assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Eosinophil Chemotactic Factor(ECF). Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Eosinophil Chemotactic Factor(ECF). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Eosinophil Chemotactic Factor(ECF), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Eosinophil Chemotactic Factor(ECF) in the samples is then determined by comparing the OD of the samples to the standard curve.

Small volumes of ECF 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.

MBS8800011 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the ECF (Eosinophil Chemotactic Factor) 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 ECF. The ELISA analytical biochemical technique of the MBS8800011 kit is based on ECF antibody-ECF antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect ECF antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, ECF. 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(%).
