Noise in Devices
Motivation
Few decades from now on, we’ll have synthetic bacteria acting like autonomous robots. They’ll produce bioplastics, food, electricity on their own. They’ll be able to precisely detect and differentiate cancer cells from normal cells. Keeping this in mind, we wish to make logic based computations in cells as precise and predictive as we have them in our laptop chips. We seek to apply efficient methods and technology to assess, predict and fix the variability in cells. Considering these things, we have designed this year’s our project.
If we were to construct a biological oscillator , we would require various genetic parts with different strengths to functions like an oscillator. Our oscillator would work only when we make it using parts, which provide complete information about their behavior w.r.t. other parts. Usually, we use a reporter protein to characterize the functionality of device and don’t pay much attention to proper controls, which can lead to erroneous results due to intrinsic and extrinsic factors. This can be called as noise in device.
Experimental Design
Noise in device arises due to various inherent properties of the device. Our study is focused to address these issues using a device, which produces two proteins gfp and rfp. Rfp producing unit acts as an internal control and our device of interest, to be characterized, can be placed at gfp producing unit. Most of the biological devices are made up of promoters, RBSs, protein coding parts and terminators. Our device is in pSB1A2 plasmid backbone in E. coli DH5alpha.
To test the role of RBSs, nature of promoters in giving rise to noise, we made six devices. All of these six devices have same RFP expressing device as internal control. Out of six, four GFP expressing devices has same inducible reporter but different RBS parts and in other two, GFP expressing devices has different constitutive promoters.
