title: An improved perifusion system for NMR study of living cells.
abstract: Isolated cells can be kept in steady-state conditions for very long periods of time when inserted into dialysis microfibers and perifused with a nutrient-containing solution. Using this system, stable 31P NMR spectra have been obtained on dog kidney tubules for a period of 13 h.
