The application of 4-iodophenol as a signal enhancer for luminol-based immunodot and Western blotting assays was investigated. Immunodetection of biotin-bovine serum albumin (BSA) using a rat anti-biotin antibody for immunodot binding and goat anti-biotin peroxidase conjugate for Western blotting assays was employed to demonstrate the signal enhancement attainable with 4-iodophenol. The addition of 4-iodophenol at a final working concentration of 52.2 microM to a light-emitting substrate, luminol, resulted in 3-fold and 10-fold signal enhancements for Western blotting and immunodot binding detection of biotin-BSA, respectively.
