Brightfield in situ hybridization (BISH) applications have significant advantages over traditional fluorescence in situ hybridization (FISH). BISH slides can be analyzed using a regular microscope while FISH slides require the use of a specialized fluorescence microscope. BISH slides allow observers for correlating the gene status (gene amplifications, gene rearrangements, and gene deletions) and tissue morphology better than FISH slides. Also, BISH slides are ideal for the permanent preservation of gene signals. Furthermore, BISH applications can be optimized using an automated tissue slide processing system. BISH applications are becoming a popular method for clinical examination of gene status for selecting cancer treatments.
