Stability measurements of the GluA biosensor. (A) Storage stability at 4°C. (B) Operational stability in aerobic (circles) and anaerobic (diamond) conditions. Current responses recorded for additions of 5 μM L-glutamic acid at 0.6 V. Standard error bars correspond to n=3 replicates. Supporting electrolyte was 0.1 M PBS (pH 7.4).
