| Prepare CaCl2 and MgCl2 monthly as 1 m stock solutions. On the day of the experiment, mix the reagents in the order listed. Bubble with 95% O2/5% CO2 for 30 min before use. The 1× Ringer’s solution should have a pH of 7.8 without 95% O2/5% CO2 and a pH of 7.3 after 30 min of bubbling with 95% O2/5% CO2.
