WebThe sandwich ELISA quantify antigens between two layers of antibodies (i.e. capture and detection antibody). The antigen to be measured must contain at least two antigenic epitope capable of binding to antibody, since at least two antibodies act in the sandwich. WebELISA (enzyme-linked immunosorbent assay) is a powerful method for detecting and quantifying specific proteins. ELISA typically requires that the antigen of interest be captured or immobilized on a solid surface and then be complexed with an antibody that is linked to an enzyme. Detection is accomplished by assessing the conjugated enzyme’s ...

WebA common ELISA assay is the sandwich ELISA in which the wells on the ELISA plate are coated with a capture antibody then an antigen is added followed by a secondary antibody which is conjugated with an enzyme (such as horseradish peroxidase).
