Materials

• Plasmids
  • pKD46
    • Coding lambda red recombinase
    • Ampiciline resistance
    • Temperature sensitive replication origin
  • pKD13
    • Kanamycin resistance gene template plasmid
  • pCP20
    • Flipase system

Procedure

• Preparation of plasmids

1. Grow up pKD46, pKD13, and pCP20 in host strains 
2. Perform minipreps to extract plasmids 

• Transformation of pKD46
  • Using the protocol of TSS method

• Generation of cassette flanked by homologous arms
