Experiment Digestion 25.07 Ruediger | |
Project Name:GFPPbd |
Procedure
PCR tube:
total volume 20 μl
- add H2O (17 μl -X-Y-Z)
- add 2 μl Ligase Buffer 10x
- add Insert 1, Insert 2(when proceeding from 3A digestion use 2 μl of each)
- add Vector (20ng needed. When proceeding from 3A digestion use 2 μl)
- Add 1 μl T4-DNA Ligase
- Incubate 10-30 min at room temperature
- heat for 20 minutes at 80°C
- store at -20°C or directly proceed to transformation

Experiment Ligation 26.07 Ruediger | |
Project Name: GFPPbd |
Procedure
- take cells from -80°C freezer and put them on ice! (every eppi contains about 400 μl cells)
- thaw cells on ice 20 minutes
- pipette 50 μl cells and 2 μl DNA into eppi still on ice!
- Incubate for 30 minutes on ice
- Heat at 42°C for 60 sec
- Incubate on ice for 5 minutes
- Add 200 μl LB Broth
- Incubate for 2 hours at 37°C (cells with lysis cassette at 30°C!!)
- Plate 50 μl and 200μl on two different LB/Agar plates with appropriate antibiotic resistance
Documentation:
Why are you doing this experiment? Name of the sample? Where are they stored? Name the vector with inserts, antibiotika resistance etc.
Had only 6 tet plates -> put 100 μl of each sample on each plate
Incubator overnight for 30°C

Continue from Experiment : Quickchange V.3 | |
Project Name: Lysis Cassette V.2 (3A assembly of quickchange-modified K098995 with Lysis genes K124017) |
Procedure
- add H2O (38μl-DNA )
- 5 μl NEB4 buffer (stored at iGEM’s, -20°C)
- 5 μl 10x BSA (used 1:10 diluted sample stored at iGEM’s, -20°C)
- DNA (500 ng) (Vector:Insert ratio 1:3 in following Ligation)
- 1 μl restriction enzymes (stored at iGEM’s, -20°C)
- heat for 1-2 hours 37°C (6 hours if time)
- heat for 20 minutes 80°C (inactivation of enzymes)
- keep at 4°C if you cannot continue
Restriction enzymes you need to cut the vector, insert1 and insert 2:

Ligation step of 3A assembly.
Length of pSB1T3= ca 2200bp Length of K124017+Vector= ca 4500bp 4500/2200= ca 2 So 2*3 µl (since 3:1 is needed) = 6 µl
