In vitro calibration of ChOx- and AChE+ChOx-coated recording sites. (A) Raw current traces depicting the responses to increasing concentrations of choline are shown, obtained from ChOx-only (red color) and AChE+ChOx-coated (orange color) recording sites. Addition of ascorbic acid (AA) and dopamine (DA) did not elicit current, reflecting the efficacy of the m-PD barrier. The responses to choline did not differ between the two coating types, indicating that co-coating with AChE did not affect the potency of ChOx. (b) Raw current traces depicting the responses to increasing concentrations of ACh. As expected, recording sites coated with ChOx only did not respond to ACh.
