抄録

A simple biosensor for measuring sodium channel blockers, such as tetrodotoxin (TTX) and saxitoxin (STX), and paralytic shellfish poisoning (PSP) consisted of frog bladder membrane, and Na<sup>+</sup> electrode. Effects of storage temperature, antiseptic and species of frog on the activity of Na<sup>+</sup> channel on the membrane were investigated from the standpoint of practical use.<br>The results obtained were as follows:<br>1) The maximum output of the sensor was obtained at 30 to 33°C and pH 4.8 to 6.0.<br>These values were shown higher in the case of tropical frog than a temperate frog. This was assumed due to the effect of living the environment.<br>2) Frog bladder was able to keep at 5°C during 7 months, but at -30°C during only 80 days.<br>3) Antiseptic effect of NaN<sub>3</sub> on the frog bladder membrane was recognized in the concentration of 0.003%.
