“…Shells of all bivalves were collected for individual age determination. Superoxide dismutase (SOD) activity was determined after Livingstone et al (1992). 100-180 mg of frozen mantle and gill tissue were ground in liquid nitrogen and homogenised with a micropistill in Tris-HCl buffer (20-mM TRIS, 1-mM EDTA, 20-mM HCl, pH 7.6) 1:10 (w/v).…”

Cell proliferation and apoptosis were investigated in tissues of two bivalve species, Arctica islandica from the German Bight (age of bivalves: 33-98 years) and Iceland (7-148 years) and Aequipecten opercularis from the English Channel (2-4 years). High proliferation rates (10% nuclei dividing) and apoptosis in tissues of A. opercularis were in line with high-energy throughput and reduced investment into antioxidant defence mechanisms in the scallop. In contrast, cell turnover was slow (\1% nuclei dividing) in A. islandica and similar in mantle, gill and adductor muscle between young and old individuals. In the heart, cell turnover rates decreased with age, which indicates less-efficient removal of damaged cells in ageing A. islandica. Cell turnover rates, mass specific respiration and antioxidant enzyme activities were similar in German Bight and Iceland ocean quahog. Variable maximum life expectancies in geographically separated A. islandica populations are determined by extrinsic factors rather than by fundamental physiological differences.

“…Samples were centrifuged for 3 min at 18,000g and at 4°C. SOD activity was measured as degree of inhibition of the reduction of cytochrome c by superoxides generated by a xanthine oxidase/xanthine system at 550 nm in 43 mM potassium buffer with 0.1 mM EDTA, pH 7.8 according to (Livingstone et al, 1992). One Unit SOD causes a 50% inhibition under the assay conditions.…”
