Isethionic acid (80% in water)
Based on 1 Customer Validation
Isethionic acid is a calcium binder and anionic detergent that enhances mitochondrial calcium binding capacity by competitively binding to calcium binding sites on the outer mitochondrial membrane. Isethionic acid can inhibit calcium-activated mitochondrial respiration. Isethionic acid inhibits barnacle (Balanus amphitrite) larvae with LC50s of 23 μg/mL (24 h) and 17 μg/mL (48 h), respectively. Isethionic acid can inhibit the attachment of barnacle larvae (complete inhibition at 10 μg/mL) and regulate mitochondrial calcium transport, and can enhance ATP-dependent calcium uptake at high calcium concentrations. Isethionic acid can be used to study the mechanism of mitochondrial calcium metabolism.

Isethionic acid (3×10-5-6×10-4; 30 min) inhibits 4 mM CaCl2-activated respiration in rat liver mitochondrial respiration assay, with a maximum inhibition rate of 85% (6×10-4 M), and does not affect phosphate production[2].
Isethionic acid (3×10-4 M; 1 min) increases calcium uptake under 10 mM Ca2+ conditions in an ATP-dependent calcium uptake assay[2].
