Laboratory work

Team:Input

UV irradiation test

  1. Incubated cultures (from Glycerol Stocks) with 2ml of LB-Ampicillin Medium for 12 hours at 37 degrees.
  2. Pre-incubated was plated so as to produce about 1000 colonies.(Ptet:1,Ptet-RFP:1,PrecA-RFP:3)
  3. We put　Negative Control　of　Prec-RFP in a dark place.
  4. To 8 new Amp plates (2.5cm or 6.5cm apart from UV source for 30sec,1min, 30min, and 1h each) cultures grown at 37°C for 12h were transfered using nitrocellulose filters.
  5. These are controls with Ptet and Ptet-RFP colonies.
  6. PrecA-RFP plates were exposed to UV(254nm) at a distance 2.5cm or 6.5cm apart.
  7. A Negative Control　of　Prec-RFP was placed in a dark place.
  8. After UV exposure for 30sec, 1min, 30min, or 1h (each with either 2.5 or 6.5cm from the UV source or without light exposure), we transfered using nitrocellulose colonies from these plates to Amp control plates.
  9. We then tested the amount of time required for RFP expression after UV exposure. To do this, we scanned in the exposed plates after the various exposure times and observed the color change.

result

We were not able to visually observe RFP fluorescence from plates containing PrecA-FRP.
