Engrailed Homeobox Protein 2 (EN2) ELISA Kit for Human

Test Principle: The microtiter plate provided in this kit has been pre-coated with an antibody specific to EN2. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to EN2. 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 EN2, 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 EN2 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Small volumes of EN2 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.

MBS459054 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Engrailed Homeobox Protein 2 (EN2) 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 EN2. The ELISA analytical biochemical technique of the MBS459054 kit is based on EN2 antibody-EN2 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect EN2 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, EN2. 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(%).
