Adenosine triphosphate (ATP) and adenosine diphosphate (ADP) are crucial molecules in cellular energy metabolism. ATP serves as the primary energy currency of the cell, while ADP is a product of ATP hydrolysis and plays a role in energy transfer and cellular signaling. The balance between ATP and ADP levels is a key indicator of cell viability, metabolic activity, and apoptosis. Assay kits for detecting ADP and ATP are critical tools in studying enzymatic activities, particularly for kinases and ATPases, which are involved in numerous cellular processes. These kits utilize various biochemical strategies to quantify nucleotide levels, offering high sensitivity and adaptability to different experimental conditions.

Importance of ADP/ATP Ratio Measurement

The ADP/ATP ratio provides valuable insights into cellular health, apoptosis, and metabolic status. Changes in this ratio can indicate:

• Cell proliferation and viability: Higher ATP levels suggest actively growing and metabolizing cells.

• Apoptosis and necrosis: Increased ADP levels or a declining ATP/ADP ratio indicate energy depletion and cell death.

• Drug screening: Evaluating the effect of compounds on cellular energy metabolism.

• Metabolic research: Studying bioenergetics in normal and diseased states, including cancer, neurodegeneration, and cardiovascular disorders.

These kits provide versatile, sensitive platforms for studying ATP-dependent processes, enabling advancements in biochemistry and drug development.
