Holding Potential | Glucose Sensitivity (nA/mM) | Glucose r2 | Glucose % Difference vs. +0.1 V | DA Sensitivity (nA/μM) | DA r2 | DA % Difference vs. +0.1 V |
---|---|---|---|---|---|---|
+0.1 V | 14.8 ± 0.4 | 0.99 | 0 | 2.1 ± 0.2 | 0.98 | 0 |
−0.1 V | 12.0 ± 0.3 | 0.99 | −18.8** | 5.0 ± 0.4 | 0.98 | 138.1* |
