Latency is defined as the time lag between a change in input concentration and the output level reaching 95% of its final value. While these measurements have not yet been made accurately. we expect that the Lux family of receivers will have very low latencies. Since the receiver protein is being constitutively produced, the only time lags are for transport of the AHL molecule through the media and into the cell, and the fast time-scale binding reactions between the receiver protein, the signaling molecule and the promoter operator site. As there are no feedback loops in the device, the response is first order.
