FISH is a molecular technique that is often used to identify and enumerate specific microbial groups. This technique can be used to determine, with the presence or absence of a fluorescent signal, whether specific genetic elements exist in a sample. This can be useful for determining if microbes have a … See more The FISH technique is dependent upon hybridizing a probe with a fluorescent tag, complementary in sequence, to a short section of DNA on a … See more Fluorescent probes of various colors can be used at the same time for varying targets at the same time to determine which portion of a population different individuals make up.
