Abstract:
The present invention provides compositions, kits, assembles of articles and methodology for detecting multiple target molecules in a sample, such as in a tissue sample. In particular, site-specific deposition of elemental metal is used in conjunction with other means of detection, such as other chromogenic, radioactive, chemiluminescent and fluorescent labeling, to simultaneously detect multiple targets, such a gene, a protein, and a chromosome, in a biological sample. More particularly the multiple targets may be labeled with the specifically deposited metal and other chromogenic labels to allow chromogenic immunohistochemical (IHC) detection in situ by using bright field light microscope.
