Task:

• Transformation of electrocompetent E. coli strain TOP10 with pKS plasmid containing hemolysin coding sequence

Procedure:

1. Ligation mixture (9 μl) was dialise 30 minut
2. Half of the volume of the mixture was added to thawed bacteria
3. Bacteria were transfered to the cuvette and electroporated (2500V, 5 sec)
4. After the electroporation 1 ml of SOB medium was added to the cuvette
5. Mixture with bacteria was transfered to the Eppendorf probe and it was incubated for 45 minut in 37 °C
6. Mixture was divided to 2 equal portion which were plated on medium containing ampicillin, X-Gal and IPTG
