Stimulus-induced Ca2+-influx in LvsA-and DH1. Ca2+-influx was determined with a Ca2+-sensitive electrode before and after addition of cAMP or AA at an extracellular Ca2+-concentration of 2–3 μM. Data are means ± SD. The number of independent experiments is given in brackets.
| Ca2+-influx pmol/107 cells | ||

| cAMP 0.1 | < 0.1 (7) | nd |
| 1 | < 0.1 (7) | 100 ± 59 (3) |
| 10 | 1 ± 5 (9) | 203 ± 107 (3) |
