A dry, removable analytical element can be used to detect chemiluminescent signals produced from the reaction of peroxidase and a chemiluminescent detection system. The analytical element contains at least two layers, the outer layer being non-tacky and water-soluble or water-permeable, and used to contact a gel plate or transblotting membrane in which multiple analytes are located. The resulting signal can be recorded using a photosensitive element. Test kits include the various packaged components needed to use the analytical element for analyte detection. Within the element are critical amounts of oxidase and an oxidase substrate for highly sensitive analyte detection.

Dry elements, test devices, test kits and methods for chemiluminescent

Dry transparent analytical elements can be used to determine analytes which have been separated by electrically induced migration through a solid medium, e.g. by electrophoresis, or which are intracellular enzymes. The dry transparent element is placed on a plate containing the analytes, and kept there until the analytes have reacted to produce a non-diffusible detectable species solely in the element. The element is removed and the detectable species is evaluated therein. The elements contain a water-insoluble binder material having an interactive composition dispersed therein which reacts with analyte to produce the non-diffusible species. The same electrophoretic plate can be used to successively determine the same or a plurality of analytes since it is not altered or destroyed by contact with the dry element.
