1. Diluted 1ng/microliter pGreen plasmid to 10pg/microliter with 100X dilution
2. 1microliter of plasmid to 50 microliters competent cells
3. Will grow up 50microliters of TOP10 untransformed as a control
4. Put on ice at 2:03
5. Took off ice at 2:34
6. Incubated for 1minute at 42C
7. Added 250microliters SOC media (prepared at 1:30)
8. Start incubated at 37C at 2:36
9. Take out at 3:40pm
10. Streaked 20microliters onto Amp. Plates
11. Dan will come in Saturday morning to pick up the plates and count colonies.

- Remade TOP10 competent cells--will try to make more competent
- Inoculated 500mL of SOB at ~10am with 1mL each of TOP10 starter culture
- Two 2L flasks with 250mL each
- At 5:30 OD was .28 and .29 for each flask respectively
- Final OD after following competent cell protocol was 1.04 (between 1-1.5 as required)
- Put into -80C at 7:30pm.

Transformation with pGreen
- 10pg/microliter on LB Amp
- 1 ng/microliter on LB Amp
- NO plasmid on LB Amp
- NO plasmid on plain LB
- Put into 37C incubator ~1:30pm
Plates
- Running out of plates
- 500mL of LB and LB Amp agar
- 100mg/mL stock of Ampicillan
- After cooling for ~45 minutes at room temp, added .5mL
- Poured around 4:30 pm. Turned over at 5:30
Checked plates before I left at ~6pm. No growth (as expected). Will look again in the morning

- Checked plates
- 10 pg/microliter plate had ~20 colonies. Competency still off by factor of 10 :(
- 1ng/microliter plate was a big streaky mess (too many to count)
- NO plasmid on LB+Amp also big streaky mess. Possibly mislabeled plate??
- NO plasmid +LB big streaky mess (as expected)
