Determination of Ca2+-release from the isolated smooth muscle cells in suspension from the guinea-pig ileum.


Collagenase-dispersed cells from the guinea-pig ileum were prepared and Ca2+ release into Ca2+-depleted solution from the isolated single cells obtained by the centrifugation of the dispersed cells on isotonic sucrose solution was determined with a Ca2+-selective electrode. A technique employing an isotonic sucrose solution for washing isolated cells… (More)
