WebAims: Different indicator enzymes and fluorogenic or chromogenic substrates were compared as detector systems in a novel polymyxin-based enzyme-linked immunosorbent assay (ELISA) for Escherichia coli O157 lipopolysaccharide (LPS) antigens. Methods and results: An ELISA system was developed using polymyxin immobilized in the wells of a … WebThe most common type of ELISA detection uses a colorimetric assay. Generally, horseradish peroxidase (HRP-) or alkaline phosphatase (AP-) conjugated antibodies are used in combination with a chromogenic substrate (eg, TMB) solution. This detection method uses absorbance to determine the readout and compares samples to each other …
