The kit is intended for determination of intracellular ATP (adenosine triphosphate) in microbial cells. Most types of somatic cells, e.g. blood cells are lysed with a neutral detergent. The released ATP and other forms of extracellular ATP in the samples is enzymatically degraded. If the intention is to determine intracellular ATP in bacterial as well as somatic cells, we suggest the 266-111 Intracellular ATP Kit without the lysing agent. All living cells contain ATP where it plays the role of energy currency between different cellular processes.nnWhen cells die of natural causes, ATP is normally degraded. The intracellular concentration of ATP is carefully regulated to similar levels in all types of cells. ATP is therefore a good estimate of the total intracellular volume. Most bacterial cells contain approx. 2*10-18 mol ATP per cell, while most eukaryotic cells, as a result of their larger size, contain 10-15 mol ATP or more. ATP Biomass Kit HS, Intracellular ATP Kit HS and Microbial ATP Kit HS contain ATP Reagent HS (High Sensitivity) with a high luciferase activity. The luciferase activity in ATP Reagent HS is actually so high that if contaminated during reconstitution it will degrade the ATP background by one order of magnitude every 38 min. After mixing sample and ATP Reagent HS the light intensity decays by approx. 6% per min.nnThis is slow enough to allow manual mixing and a tube luminometer without reagent dispenser can be used. The detection limit of the reagent is 10*10-18 mol ATP with a sensitive luminometer. This corresponds to 5 bacterial cells. We must here differentiate between bacterial cells and CFU, since one CFU may consist of several cells. If the detection limit is not adequate, it is possible to concentrate the sample by microfiltration, a procedure that will also remove extracellular ATP (please contact BioThema for further information).
