Quantitive determination of flavin nucleotide using the bacterial bioluminescent reaction
Photometric method based on the use of bacterial luminiscent reaction quantitatively detects the presence of flavin compounds in all forms of life. Aqueous cellular dispersion of a biological sample with an aqueous perchloric acid ruptures the cells and frees the flavin coenzymes from their proteins.
