Some samples of broadly utilized assays that include labels incorporate the Gram stain, that's used for the identification and characterization of microbes; fluorescence in situ hybridization, and that is utilized for the detection of precise genetic sequences in chromosomes; and luciferase assays, which measure bioluminescence produced from luciferin-luciferase reactions, allowing for to the quantification of a big range of molecules.
