A new method for lowering the detection limit for a horseradish peroxidase (HRP) label in an enzyme-linked immunosorbent assay (ELISA) is proposed. The method is based on the use of a photochemical reaction of o-phenylenediamine (o-PD) autosensitized oxidation as an enhancement step in ELISA. The as

β¦ Synopsis
A sensitive assay highly specific for horseradish peroxidase has been developed. The basic principle of the procedure is similar to that of the enzyme-linked immunosorbent assay technique. Sensitivity is the range 0.156-2.5 ng/ml. Background activity in undiluted plasma and lymph under these conditions is negligible.
