Abstract: A method and system to enhance analysis of electrophoretic bands by overlaying only the pixels of interest. The overlaid pixels are superimposed as a layer above, i.e., in the foreground of, the overlaid image, i.e., in the background. A user employs the superimposed pixels for molecular weight determination and is still able to generate densitometry analysis of the remaining pixels in the overlaid image.

Abstract: Chemiluminescent detection of molecules of synthetic or natural origin such as proteins and nucleic acids (DNA and RNA), as well as other biologic molecules, is increasingly replacing radioactive detection as the method of choice where sensitivity is critical. In such assays, luminescence is customarily achieved by the oxidation of a luminol or isoluminol substrate in the presence of an oxidizing agent such as hydrogen peroxide or hydrogen peroxide source, such as perborate, and a peroxidase catalyst such as horseradish peroxidase. To obtain useful levels of luminescence (e.g., detectable levels) by customary techniques, a luminescent enhancer is also present during oxidation. It has been found in the practice of the present invention that azine enhancers have contained an impurity which reduces the properties of the chemiluminescent assay working solutions.

Abstract: Novel symmetrical and asymmetrical 10,10′-substituted-9,9′-biacridines and the synthesis of such symmetrical and asymmetrical 10,10′-substituted-9,9′-biacridine molecules and their derivatives is disclosed. These molecules are shown to produce light by chemiluminescence in the presence of signal solutions. These symmetrical or asymmetrical 10,10′-substituted-9,9′-biacridines are used alone or attached to haptens or macromolecules and are utilized as labels in the preparation of chemiluminescent, homogeneous or heterogeneous assays. They are also used in conjunction with other chemiluminescent label molecules to produce multiple analyte chemiluminescent assays.
