Immunoplates, also known as ELISA plates, are laboratory tools used in immunology research to detect and measure the presence of specific antigens or antibodies in biological samples. These plates are typically made of plastic or polystyrene and have multiple wells, usually ranging from 96 to 384 wells, that are coated with an antibody or antigen.
The sample is added to the wells, and if the antigen or antibody of interest is present in the sample, it will bind to the immobilized antigen or antibody on the plate. A detection system is then used to visualize and measure the amount of bound antigen or antibody.
