3A-assembly: Digest

Investigators: Jakob

3A-assembly of S22 (ho1)+S21a (terminator) and S23 (pcyA)+S21a (terminator)


Digestion


Name:Jakob Date: 14.07.2011
Project Name: 3A-assembly of pcyA+ terminator, ho1+terminator

 


Procedure

 

1. add H2O (16μl-DNA )   

2. 2μl NEB4 buffer

3. 2 μl 10x BSA     (used 1:10 diluted )

4. DNA (500 ng) (Vector:Insert ratio 1:3 in following Ligation)

5. 1 μl restriction enzymes

6. heat for 1-2 hours 37°C (6 hours if time)

7. heat for 20 minutes 80°C (inactivation of enzymes)

8. keep at 4°C if you cannot continue

 

Measured DNA-concentration with Nanodrop to calculate the volume of DNA to do the digestion:


Sample Name DNA concentration (μg/μl)
Vector  pSB1T3 20
terminator 38.8
ho1 176
pcyA 173

 

Restriction enzymes you need to cut the vector, insert1 and insert 2:

Enzyme 1 (1μl)  EcoRI  EcoRI  XbaI
Enzyme 2 (1μl)  PstI  SpeI  PstI
H2O (14 μl- DNA)      
In total 20 μl      

 

3A-assembly: Ligation and transformation

Investigators: Julia

Ligation of S22 (ho1)+S21a (terminator) and S23 (pcyA)+S21a (terminator) in vector pSB1T3.

L23: Ligation of S23+S21a in pSB1T3 L22: Ligation of S22+S21a in pSB1T3 Ligation

Experiment     3A-assembly

Project Name:3A-assembly of pcyA+ terminator, ho1+terminator

 


Procedure

total volume 20 μl


1. add H2O(17 μl -X-Y-Z)

2. add 2 μl Ligase Buffer 10x

3. add Insert 1, Insert 2 (when proceeding from 3A digestion use 2 μl of each)

4. add Vector (20ng needed. When proceeding from 3A digestion use 2 μl)

5. Add 1 μl T4-DNA Ligase

6. Incubate  10-30 min at room temperature

7. heat for 20 minutes at 80°C

8. store at -20°C or directly proceed to transformation
