A diagnostic means for luminometric assay of ATP, comprising a reagent carrier, optionally attached to a substrate, and a reagent for said assay in dried form on said carrier; a diagnostic kit for luminometric assay of cellular ATP, comprising: a) cuvettes containing buffering solution; b) a first diagnostic means containing a bioluminescence reagent and a second diagnostic means for sampling, or, alternatively, a combined diagnostic means containing both reagent and sampling functions; and optionally c) accompanying directions as how to use the kit; a method for luminometric assay of cellular ATP in a liquid sample, comprising the steps: a) sampling an aliquot of said sample with a sampling element that may contain pretreatment reagents, which during an incubation period affects the ATP level of the sample to make it a more reliable estimate of the cellular ATP level; b) rapidly heating said aliquot without dilution to a controlled temperature around 100 DEG C capable of almost instantaneous inactivation of ATP degrading enzymes present in said aliquot or in pretreatment reagents and furthermore capable of an almost complete release of cellular ATP but not so high as to destroy ATP; c) transferring the aliquot from step b) above to a buffering solution together with a bioluminescence reagent; and d) measuring light emission to determine the cellular ATP content. |
