pKD46 plasmid, 2 ug

pKD46 is a temperature-sensitive plasmid that expresses the λ-Red recombination system (gam, bet, and exo genes) under the control of the araBAD promoter. It is widely used for high-efficiency recombineering in E. coli, allowing precise insertion, deletion, or modification of DNA sequences in the bacterial chromosome.

This plasmid is ideal for researchers performing gene knockouts, gene replacement, and synthetic biology applications in E. coli strains such as DH10B, MG1655, and K-12 derivatives.
