for ATP determination

Fireflies have been used in several studies of bioluminescence. In particular they may be used in assays to determine toxicity pathways because bioluminescence can quantitatively measure a wide range of biological activities.Firefly Lantern Extract has been used in the detection of ATP concentrations by bioluminescence flash analysis in seawater samples, bioluminescence assay in river sediments samples, marine sediments and in quantifying extracellular ATP in red blood cells.应用： The bioluminescent organism, Photinus pyralis firefly is the source of firefly lantern extract. The luciferase enzyme is 60 kDa enzyme which lacks prosthetic group and bound metal in its structure. The N-terminal harbors residues crucial for the bioluminescent activity and the C-terminal possess peroxisome targeting motif.
