WebDirect detection is suitable for detecting highly expressed antigens. For direct detection, the primary antibody can be conjugated to an enzyme, such as horse radish peroxidase (HRP) or alkaline phosphatase (AP), or a fluorochrome. The benefit of direct detection is that an additional incubation step with a secondary reagent is not necessary. WebThe most popular methods of detection are with enzyme- and fluorophore-mediated chromogenic and fluorescent detection, respectively. With chromogenic reporters, an enzyme label is reacted with a substrate to yield an intensely colored product that precipitates at sites where antigen is found. eastwood park penryn
