It seems that too much template DNA was used hence the bands did not travel far


Liquid Culture with DAM- E. coli in LB

Thursday, June 26, 2014

1. Set up 3 liquid cultures with 4 ml of LB each and 4 ul of Ampicillin (1:1000 Concentration)

2. Incubated in 37˚C shaker overnight


Mini-Prep DAM- Negative Liquid Culture

Friday, June 27, 2014

Buffer Preparation:

Resuspension Solution: add provided RNAse Al store at 4˚C for up to 6 months

Wash Solution: Add 35 ml of 96% EtOH to 20 ml wash solution. Store at room temperature (RT); we have 100% EtOH

1. Pipet 1.5 mL of culture into microcentrifuge tube and spin for 2 minutes

2. Resuspend pellet in 250 mL of Resuspension solution

3. Add 250 mL of Lysis solution and mix by inverting tube

4. Add 360 mL of neutralization and mix immediately by inversion 4-6 times

5. Centrifuge for 5 minutes to pellet cell debris

6. Transfer supernatant to spin column

7. Centrifuge for 1 minute and discard flow through

8. Add 500 mL of wash solution and centrifuge for 30-60 seconds and discard flow through

9. Repeat wash using 500 mL of wash solution

10. Transfer spin column to fresh 1.5 mL tubes and add 50 mL of elution buffer to center of column

11. Incubate at RT for 2 minutes centrifuge for 2 minutes

12. Store flow through (purified plasmid DNA) at -20 degree Celsius.
