Listeriolysin O (LLO) ELISA Kit for Pig

Principle of the Assay: This assay employs a two-site sandwich ELISA to quantitate LLO in samples. An antibody specific for LLO has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLLO present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LLO is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LLO bound in the initial step. The color development is stopped and the intensity of the color is measured.

Small volumes of LLO 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.

MBS284933 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Listeriolysin O (LLO) 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 LLO. The ELISA analytical biochemical technique of the MBS284933 kit is based on LLO antibody-LLO antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect LLO antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, LLO. 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(%).
