Abstract [en]

In single Fura-2 ester-loaded hepatocytes, stimulation by vasopressin, but not emptying of the agonist-sensitive Ca2+ store by 2,5-di-(t-butyl)hydroquinone, resulted in an increase in the rate of Fura-2 fluorescence-quenching by Mn2+. Similarly, in cells microinjected with Fura-2 salt, vasopressin stimulated Mn2+ entry while 2,5-di-(t-butyl)hydroquinone or thapsigargin did not. The pattern of Fura-2 quenching by Mn2+ only correlated with the movement of Mn2+ across the plasma membrane.
