text: There are many reasons for extracting and measuring ATP from cells, but they may be placed into one of two main categories: (1) the level of endogenous ATP in a cell may be used as an index of energy status, and it is therefore useful in metabolic and physiological studies; (2) estimates of cell numbers in microbial and tissue cultures may be obtained after assuming that the ATP per cell remains at a fairly constant (within a factor of five) and known value under defined conditions.
