Quantitation of cellular adenylate levels (i.e., ATP, ADP, AMP) has widespread applications in physiological, metabolic and energetic studies. We have compared classical adenylate extraction procedures (i.e., perchloric acid, boiling) with a previously unreported proteinase K-based extraction technique. Our results suggest that all three techniques are comparable in soft animal tissue, but proteinase K-based extractions consistently generated higher adenylate yields from a broad range of organisms, particularly those containing a cell wall (e.g., alga, bacteria, fungi, plant).
