Week1
Construct Red Sensor plasmid.
Considering low copy number of pCDDuet, we change the constitute promoter into T7 promoter, an inducible one.
PCR from constructed cph8-pSB1C3 plasmid to get cph8 sequence combined with terminator (adding restriction enzyme cutting sites, Nco I and Hind III).
Digest cph8-ter sequence and pCDFDuet with Nco I, 6 hours and Hind III, 1 hour.
Ligation and transformation. (3 hours, DH5α). Culturing overnight.
Plasmid of cph8-pCDFDuet of constitutive promoter is confirmed by sequencing.
Overlap PCR to get sgRNA sequence.
Construct green Sensor plasmid.
Sequence of green sensors on pCDFDuet dis confirmed by sequencing.
Inserted sgRNA is confirmed by PCR and digestion.
Co-transformation: RFP, green sensor with sgRNA, dCas, segment.
Get the Blue sensing part
After getting the blue sensing part, next we will link the sgRNA to it
Week2
Construct Red Sensor plasmid.
Picking colonies of T7 promoter and culturing 12 hours.
Extract the plasmid through miniprep. Identification by PCR, using primers of cph8 and primers on pCDFDuet).
Picking samples with positive results, identification by digestion(Kpn I and Hind III).
Digest cph8-pCDFDuet and sgRNA with Kpn I, 6 hours and Hind III, 1 hour.
Ligation and transformation. (3 hours, DH5α). Culturing overnight.
Picking colonies of constitutive promoter and culturing 12 hours.
Keep Ligating
Strange things keep happening and we have to ligate the sgRNA to it. So harsh.
Week3
Construct Red Sensor plasmid.
Extract the plasmid through miniprep. Identification by PCR, using primers of cph8 and primers of sgRNA).
Picking samples with positive results, identification by digestion(Xba I and Hind III).
No positive results, ligation and transformation again.
Sensor+sgRNA of blue light controlled gene regulating system
Finally we get the right plasmid, next we need to test its function. Ready to set case group and control group.
