產品說明:

A a K strain bacterium, carries mutations in recA and endA, leading to minimal recombination and improved quality of isolated plasmid DNA.

Carries the F’ episome which allows blue/white screening for recombinant DNA.

A popular strain for routine subcloning.

Utilized for single-stranded DNA rescue when M13 or phagemid systems are used simultaneously.

Sensitive to all common antibiotics.

This product can become a powerful cloning tool when it is used in combination with ligase.

Grows fast, colonies to show up within 8 hours. Try this strain when you are in urgent.
