Lal, R. (1999) Cloning vector and a process for the preparation thereof. US patent No. 005985560A page 1-25

This invention relates to a method for the preparation of a series of cloning vectors and such cloning vectors prepared there form. The method consists of digestion of pRL derivative with a restriction enzyme Bam HI and digestion of pIJ4026 by Bgl II and electoeluting the ermE gene. The linear DNA having pRL1 derivative was ligated with ermE gene and then transformed into E.coli GM2163. The transformants were screened for the presence of concatamers and the concatamers of pRL80 DNA were isolated from E.coli . The transformants were selected under appropriate antibiotics selection pressure.
