Sensitive ATP Detection

Sensitive ATP Detection

Sensitive ATP detection, especially in low-concentration samples, is critical for studies in energy metabolism and cell viability. The Tribioscience ATP Colorimetric and Fluorometric Assay Kit addresses this need with a straightforward and efficient method that enables detection of ATP concentrations as low as 0.5 µM. Utilizing a reaction that phosphorylates glycerol, the assay produces a measurable signal that can be captured using colorimetric (OD at 570 nm) or fluorometric (Ex/Em = 535/590 nm) techniques, allowing researchers to choose the most suitable format based on their sensitivity requirements.

The kit’s fluorometric mode significantly enhances sensitivity—up to 100-fold compared to the colorimetric version—making it particularly well-suited for samples where ATP is present at very low levels. By using just 10 µL of sample in a 96-well plate format, the assay supports high-throughput screening while maintaining precision. The flexible detection range of 0.5–1000 µM ensures reliable quantification across diverse sample types, including cells and tissues. This feature is especially valuable when studying ATP dynamics in minimal or precious biological material.

To further support sensitivity and reproducibility, the protocol emphasizes proper sample preparation, including rapid freezing and centrifugation to preserve ATP stability. A linear regression-based standard curve enables accurate calculation of ATP concentrations, ensuring dependable results even at the lower detection limits. Overall, the Tribioscience ATP assay kit offers a robust solution for researchers requiring enhanced sensitivity in ATP measurement, especially for applications involving trace-level detection in small or low-yield samples.
