Fig. 6From: Layering genetic circuits to build a single cell, bacterial half adderDesign and characterisation of the biological half adder. a Genetic blueprint of the half adder. b Digital performance of the half adder at steady state. c Flow cytometry analysis of the half adder. The Y axis coordinate represents population count, while FITC-A and PE-CF594-A represent channels that detect GFP and RFP fluorescence, respectively. Population shifts to the right represent ON behaviour. Error bars represent the standard deviation of four independent experimentsBack to article page
