bookmark HD FISH / High-Definition DNA FISH Allows high-definition of DNA fluorescence in situ hybridization (FISH). HD FISH can operate at the resolution limit of conventional optical microscopy due to the systematic design of unique probes with short span. It enables visualization of virtually any human or mouse genomic locus. This tool allows users to fully exploit the potential of DNA FISH. It provides human and mouse genomic libraries of polymerase chain reaction (PCR) primer pairs with optimal thermodynamic features.
