How can I deal with a signal drift?

There are several ways to avoid a drift of the signal. First, lower the LED excitation power to below 0.5. If the drift is already visible in the baseline, you can perform a Cyto chip test which includes a bleaching step. If the signal still drifts, you should thoroughly clean the device by performing 1-3 x System Washes. Do not use the camera during a measurement.
