This paper decribes the use of the Ca~2+-sensitive neutral carrier ETH 1001 to prepare calcium ion-sensitive microelectrode (Ca~2+-ISM). Its outer diameter is less than 0.7μm. Between pCa_3 3(PCa3…) and 7, the per decade potential change in [Ca~2+] of the Ca~2+-ISM is 25.4mV and the lowest Ca~2+ detecting concentration is 10~(-8M). The intracellular Ca~(2+) activity (0_(ca)~i) and cellular resting membrane potential (E_M) of frog's sartorius muscle were detected simultaneously. The results showed that: α_(ca)~i =-0.11μM, E_M =-79.0mV. By altering the potassiun ionic concentration[K~+]_0 and calcium ionic concentration [Ca~(2+)]_0 of Ringer's solution, the dynamic changes of α_(ca)~i, and E_M were measured. The results are as follows: (1) when [K~+]_0 was increased from 3.5mM to 10.0mM, (α_(ca)~i) increased from 0.11μM to 0.15μM, E_M fell from -79.0mV to-67.7mV; (2) when FCa~(2+)]_0 was decreased from 1.8mM to 1.0mM, α_(ca)~i decreased from 0.11μM to 0.03μM and E_M fell from -79.0mV to-73.8 mV. Our results also show that Ca~(2+)-ISM is one of the direct, convenient and effective means in the dynamic detection of intracellular calcium ion.
