Labelled immunoassays

WebEnzyme immunoassays (enzyme-linked immunosorbent assays, or ELISA; immunometric assays) use enzymes as labels, such as, for example, horseradish peroxidase or alkaline phosphatase. Chemiluminescent immunoassays (CIA) use luminol. Fluorimetric immunoassays (FIA) use fluorescent compounds (e.g., fluorescein) as labels. View … WebMost types of immunoassays also incorporate a ‘label’ whose purpose is to provide measurability. Assays are classed as ‘direct’ if the label is conjugated to the primary antibody or ‘indirect’ if the label is attached to another molecule, called a ‘secondary reagent’. Labels include but are not limited to organic dyes,
