## Abstract The (Na + K)βactivated adenosinetriphosphatase (NaK ATPase) has been purified from Lubrol extracts of membranes from the rectal glands of Squalus acanthias. The specific activity of the purified enzyme is 2 to 3 times that previously reported by others after correction of their specific
Determinants of the steady-state vol of the dogfish shark (Squalus acanthias) rectal gland cells were studied. The cellular levels of trimethylamine oxide (TMAO) in fresh tissue and slices incubated aerobically 60 min in standard (TMAO-free) elasmobranch saline were close to those in the plasma (71
