Description
Quantity: 1 Kit
Unit Size: Each
Features of the ATP Determination Kit include:
• Utilizes a luminescence-based system to monitor light emission, enabling sensitive and accurate quantification of ATP levels
• Offers exceptional sensitivity, capable of detecting as little as 0.1 picomole of pre-existing ATP or ATP generated in kinetic systems
• Employs a unique formulation where the luciferase and luciferin components are packaged separately, allowing researchers to optimize assay conditions for their specific samples and instruments
• Includes a generous supply of reagents, sufficient for performing 200 ATP assays using 500 μL sample volumes or 1,000 ATP assays using 100 μL sample volumes (enough for ten 96-well plate assays)
• Facilitates quantitative analysis of ATP levels in a wide range of biological and environmental samples and experimental systems
• Leverages the highly specific and sensitive bioluminescence reaction between luciferin and luciferase in the presence of ATP, providing a reliable and reproducible method for ATP quantification
• Compatible with various luminometers and microplate readers with a luminescence mode, making it a versatile tool for ATP detection in diverse research settingsPrinciple of the ATP-dependent bioluminescent reactionThe ATP Determination Kit is based on the absolute requirement of luciferase for ATP to produce light. In the presence of Mg^2+, the luciferase enzyme catalyzes the reaction of luciferin, ATP, and O_2 to form oxyluciferin, AMP, CO_2, pyrophosphate, and light with an emission of approximately 560 nm at pH 7.8. The luminescent signal generated is directly proportional to the amount of ATP, allowing for the measurement of ATP levels.Measure ATP levels in solution or cell lysatesThe assay reagents in the ATP Determination Kit are not permeable to live and intact cells, making this assay suitable for measuring extracellular ATP or ATP from samples in solution. To measure intracellular ATP levels for cell health or viability assays, cell lysis is required to release ATP from the cells. Lysis buffer options that are compatible with the luciferase-luciferin reaction include the Pierce Luciferase Cell Lysis Buffer (2X) (Cat. No. 16189) and the 20X cell lysis buffer formulation listed below. The 20X buffer should be diluted 1:20 with water and used immediately for cell lysis prior to running the luciferase ATP assay.20X lysis buffer:
• 200 mM Tris (pH 7.5)
• 2 M NaCl
• 20 mM EDTA
• 0.2% Triton X-100Comprehensive and versatile ATP assay kitATP is a critical molecule found in all living cells and is the energy source for various biological processes, including muscle contraction, nerve impulse propagation, and biochemical synthesis. ATP levels are often measured to determine cellular viability and metabolism, assess mitochondria function and activity, or detect bacterial and microbial contamination. This luciferase-based ATP detection kit provides a versatile and sensitive method for measuring ATP production in various enzymatic reactions, including ATPase and NADPH oxidase, and monitoring ATP release from cells. The luciferin–luciferase luminescence assay can be used to detect low-level bacterial contamination in biological samples such as blood, milk, and urine, along with environmental samples for testing of water, soil, and sludge. ATP detection has also been used to study the effects of antibiotics on bacterial populations, determine cell proliferation and cytotoxicity in both bacterial and mammalian cells, and distinguish cytostatic versus cytocidal potential of anticancer drugs on malignant cell growth.
