Mini prep on Tyrosinase
I performed a mini prep on overnight cultures of inoculated site direct mutagenesis tyrosinase from colonies #: 2, 4, 6 & 8. The method was according to the procedure described under Protocols.
spectrophotometer:
Fusionprotein of IgG protease & protein A (ZZ domain)
Digestion of protein A ZZ domain in bank vector C
- DNA vector 2 ul
- H2O 14 ul
- 10X fast digest buffer 2 ul
- Restriction enzyme SpeI 1 ul
- Restriction enzyme AgeI 1 ul
Digestion of IgG protease in bank vector C
This construct has previously been cut with the restriction enzyme NgoMIV (9/8-2010)and undergone a gel clean up.
- DNA vector 2 ul
- H2O 15 ul
- 10X fast digest buffer 2 ul
- Restriction enzyme SpeI 1 ul
Incubated both digest samples in 37 °C for 5 min.
Ligation of the digest samples
I made two versions of the ligation: # 1 & 2.
- 1:
- IgG vector 1 ul
- protein A gene 1 ul
- quick ligase 1 ul
- 2X ligase buffer 2.5 ul
- 2:
- IgG vector 1.5 ul
- protein A gene 2 ul
- quick ligase 1 ul
- 2X ligase buffer 3 ul
Incubated both ligate samples in RT for 15 min.
Transform the ligate samples
I transformed both of the ligated samples in each 100 ul Top 10 cells. The transformation method is according to the procedure decribed in protocols. However in the step 1 I thawed for 15 min instead of 10 min. In step 2 I added 3 ul of DNA, in step 6 I used LB instead of SOC and finally in step 10 I spread 100 ul of sample on a chloramphenicol plate.
