Description

The Universal USER Cassette enables the construction of USER compatible vectors by ligation of an unphosphorylated double-stranded oligonucleotide cassette into any blunt-ended phosphorylated vector. Once the cassette is ligated into the vector of choice, this vector is digested with nicking enzyme Nt.BbvCI and the restriction enzyme XbaI which creates DNA overhangs compatible with the USER processed PCR product described in the USER Friendly PCR Cloning Kit NEB #E5500).

Quality Control

Quality Assurance Statement

  • The DNA sequence of the cassette was confirmed by DNA sequencing after cloning the Universal USER Cassette into LITMUS 38 digested with StuI. Using either the High Concentration T4 DNA Ligase Reaction protocol or Quick Ligation Reaction protocol outlined below, 20-40% of transformants had the cassette inserted into the vector.
