Linear range of R123 detection. Clariostar fluorescence readings of rhodamine-123 (R123) measured as sample extracts in 30 µl Corning microplate (see Methods). Samples analyzed were P4 plasma (blue circle), P14 plasma (red square), adult plasma (green triangle), P4 brain extract (purple inverted triangle), P14 brain extract (orange diamond), adult brain extract (black large circle) and adult CSF (brown square). Note the similarity (overlap) of samples over the linear range. Representative equation for all data points: y = 0.96x + 7.8; R2 = 0.98
