This group of filter sets includes single band sets from the 49300 series as well as several multi band filter sets which are useful in FISH imaging and whole-chromosome painting applications. The multi band sets include complete dual and triple band sets but also include the 89082 and 89083 sets which are the most versatile FISH sets. These two sets contain single, dual and triple band excitation filters. This combination offers the worker the convenience of dual or triple fluorescent probe detection but also the selectivity of single probe detection. These sets are intended for use with non-laser light sources.
