IGEM:UC Berkeley/2006/Procedure Overview (Plasmid DNA to Sequencing)

1. Plasmid DNA
Path 1
- Restriction Digest of Plasmid DNA
- Run a Gel to separate parts
- Gel purify the desired part (not always going to be the shorter or longer band- could be either)
- Result: Double stranded linear DNA with sticky ends
Path 2
- PCR desired Plasmid
- Run an analytical gel to determine whether PCR worked correctly
- Result is liner double stranded DNA in buffer
- PCR cleanup
- Result is linear double stranded DNA in H2O
- Restriction Digest
- Cleanup- take only the strands that we want to insert into plasmid
- Result: Double stranded linear DNA with sticky ends

2. Ligation
- DNA ligase connects double stranded fragements of DNA with reverse complement sticky ends
- Result: Relaxed double stranded circular DNA

3. Transformation- insert new plasmid into cell
- Plate
- Observe results- are they expected or unusual?

4. Grow up colonies of cells in LB

5. Screen
Path 1
- Mini prep
- Restriction Map
- Result: Indentified clones
Path 2
- Colony PCR
- Result: Indentified clones

6. Sequence- is plasmid what it should be?
