In a traditional (direct coating) ELISA, antigens are directly attached to the plate by passive adsorption, usually using a carbonate/bicarbonate buffer at pH >9. Most but not all proteins bind tightly to the polystyrene surface of microplates in alkaline conditions.

Coating means the immobilization of antigen, antibodies or any other compound on the well surface for the purpose of a binding assay. The coated plate is part of a commercial ELISA kit or of a home-brew (self-made) ELISA assay and the term ELISA coating is often used instead.

ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology.

General ELISA protocols for Sandwich enzyme-linked immunosorbent assays (ELISA), detailing both colorimetric and chemiluminescent detection methods.

2022年11月28日 · A sandwich ELISA starts with coating the carefully selected capture antibody onto the ELISA plate. The typical coating concentration for an ELISA Flex kit from Mabtech is 2 µg/ml.

Coating buffers stabilize the antigen or antibody which is used to coat the ELISA multiwell plate, maximizing adsorption to the plate and optimizing interactions with the detection antibody.

2013年4月15日 · Here, we illustrate the process and concept behind the initial steps of a Sandwich ELISA: coating an ELISA plate with a capture antibody and then blocking the plate with BSA or a detergent-based...

OriGene ELISA-validated capture antibodies are tested on Corning-Costar High-Binding stripwell plates, #2592. Other Corning-Costar high-binding plates should give similar results. Similar plates from Nunc and Greiner may also give acceptable results, but …
