|Title||Method of amplifying ATP and use thereof|
The ATP amplification method is a method for amplifying and detecting a very trace amount of exogenous ATP by allowing a fusion protein (PPK-ADK) of a polyphosphate kinase and an adenylate kinase, the fusion protein not containing ADP, to act on a mixture of ATP, AMP, and a polyphosphate compound.
Also provided is an ultrasensitive ATP amplification method by which ATP at a single cell level can be amplified and detected, and an ultrasensitive microbial assay based on this ATP amplification method.
|Scope of claims||
1. A kit for detecting the presence of a microorganism, comprising an adenosine triphosphate amplification reagent containing adenosine monophosphate, a polyphosphate compound, and a fusion protein that has a polyphosphate kinase and an adenylate kinase in this order from the N-terminal; and an adenosine triphosphate detection reagent for detecting adenosine triphosphate, wherein the fusion protein has been subjected to an apyrase treatment and a pyrophosphate treatment so as to remove adenosine diphosphate bound to the fusion protein and wherein the fusion protein is not present in a complex with adenosine diphosphate.
2. The kit of claim 1, further comprising a cell lysis reagent.
3. A fusion protein that has a polyphosphate kinase and an adenylate kinase in this order from the N-terminal and that has been subjected to an apyrase treatment and a pyrophosphate treatment so as to remove adenosine diphosphate bound to the fusion protein, wherein the fusion protein is not present in a complex with adenosine diphosphate.
