Lab Progress
May 21st, 2008:- Resctriction enzyme digest was done on the J-brick with EcoRI. Gel was run on the J-brick after the restriction digest. No DNA was detected on the gel (the ladder was visible on the gel).
- Prepared TOP10 Competent cells for eventual transformation.
- Performed Mini-prep on Reporter+ Cells
- Performed Digest and Gel on Reporter plasmid extract -- no DNA present, suggest follow-up maxi-prep
- Transformed Top10 cells with Puc19 to ensure that the competent cell procedure was successful. Growth was observed, therefore procedure was successful.
- Diluted Reporter cells 1/1000 with 5ul Kan/mL culture for 16h incubation at 5:30pm. To be used for Maxiprep at 9:30am-1:30pm.
- Ran gel on Elowitz reporter DNA cut with EcoR1; 2 bands
- 0.7 kb and 2.0 kb, confirms identity of reporter DNA.
- Seeded syn-I and J-40001 into amp/kan LB and kan LB.
May 29th, 2008:
- Growth of J-brick in culture - No growth of I-brick on culture
- Seeded J-brick for Midi-Prep in 40mL LB with ampicillin
- Transformed TOP10 cells with both I brick and Reporter Plasmid
- Growth of I-brick on culture
- Midi-prep of both I and J brick followed by gel
- Gel indicates no presence of DNA, will be confirmed by spectrophotometric assay
June 3rd, 2008:
- Seeding of 5mL cultures of both I and J brick
- Identity of colonies on I brick plates is suspect, must ensure that eventual DNA gel confirms exact restriction digest
June 4th, 2008:
- Midiprep was done on the I and the J-brick. Once the isopropanol was added, the J-brick midiprep looked clear (no DNA was eluted). DNA gel needs to be done to confirm presence of DNA in both cases.
June 9th, 2008:
- Seeded J and I-brick re-seeded for Maxi-Prep
- Gel failed to confirm presence of previously collected DNA samples of J and I-brick, will be repeated following Maxi-Prep.
June 10th, 2008:
- Since no growth was observed in the I-brick culture, the I brick was re-seeded.
- The J-brick was diluted in 500-ml of LB broth(for a Maxiprep to be done the next day).
- Maxiprep of the J-brick.
- Restriction digest of J-brick.
- Dilution of I-brick in 500-ml of LB broth.
