Olfactory neurons from the channel catfish, Ictalurus punctatus, were isolated by a brief (15 min) treatment with papain. After incubation with fura-2 acetoxymethyl ester (fura-2/AM) for 1 h, the isolated olfactory receptor cells are found to hydrolyze fura-2/AM to fura-2 free acid without detectable traces of intermediate products of hydrolysis. Intracellular calcium measured with fura-2 in single cells covers a wide range (from less than 2 to 100 nM with a median of 17.6 nM, n = 140 cells… CONTINUE READING
