Testing:
- Temperature-test and Arabinose/IPTG-test UT3 (See below for protocol)
- Plate-test UT2, UT3, DH5a, UT13, I13522 (See below for protocol)
Andy:
- Gel-extrated R0011 (2005) S/P (band: 2000 - correct)
- Cannot gel-extract I13507 (2005) X/P because there was no more extraction column (bands: 2500-3000, 2000-2500, 750-1000 - correct)
- Transformed R0011 (2005), I13522 (2006), I13504 (2005/2006)
- Quantitated
- Q3400 (2005) E/X (no band)
- Q4400 (2005) E/X (band: 5000 - correct 120 ng/uL)
- Q3400 (2006) E/X (band: 5000 - correct 24 ng/uL)
- Q4400 (2006) E/X (band: 5000 - correct 120 ng/uL)
- UT1 D E/S (band: 2500-3000 - correct 18 ng/uL)
- UT1 E E/S (band: 2500-3000 - correct 12 ng/uL)
- UT1 F E/S (band: 2500-3000 - correct 30 ng/uL)
- o/n of UT3 x 5, UT2 x 1, and DH5a x 4 for temperature, arabinose, and plate testing
To-do List:
- Ligate UT1 with Q3400 (2006), Q4400 (2005/2006)
- Make o/n of I13522 (2006) for miniprep and plate-test, I13504 (2005/2006), I13507 (2005) for miniprep
- Gel-extract I13507 (2005) X/P
- Temperature, arabinose, and plate testing
- Purchase gel-extraction kit, make Amp plates
Guidelines for Plate-test:
- On an Amp plate, make 4 sectors (500 uL?) with varying arabinose (0.02%, 0.2%, 2%, 20%) and making sure they don’t touch each other (otherwise diffusion will happen and they’ll be the same concentration), let the arabinose area dry.
- Take o/n of UT3-DH5a and take out 200 uL and add 800 uL of fresh LB and incubate for 1 hr.
- Spin down the cells at 3000 RPM for 5 min and remove 800 uL of supernatant. Resuspend cells with the remaining 200 uL and gently spread onto plate
Guidelines for Temperature-test:
- Put a constant amount of arabinose (either 0.02% or 0.2% - don’t want TOO much repression) in each dilution.
- Grow dilutions at 37C until the absorbance is ~0.6 using the GFP ABS program. Then take some tubes out and put 1 mL into an Eppendorf tube.
- Use the white filter caps and put them on each Eppendorf tube (to allow air in, but to protect against contamination)
- Set mixer to the equivalent to the shaker in the incubator (remember it’s a smaller tube, so there probably needs to be more force on it to get it to shake).
- Set temperature to 22C
- Check the absorbance after a couple of hours and prepare the samples when the absorbance matches the absorbance of the tubs in the incubator (these should be ready before the 22C ones are ready)
- Hopefully we’ll see a significant difference in fluorescence: cold should fluoresce less than hot.
