CYCV19 One Step Seamless Cloning Kit | Single Fragment

CYCV19 is a seamless cloning kit that does not rely on T4 ligase or on restriction sites. A special enzyme mix recombines a linearized vector with a PCR fragment carrying 16-25 bp of overlap at each end. In 30 minutes a 50 bp to 15 kb blunt-end PCR fragment can be inserted at any site of any vector.
