Abstract From the Canadian patent

Messenger RNA of prorennin is extracted from the fourth stomach of calf and the double-stranded prorennin cDNA is prepared therefrom. The prorennin cDNA is cloned into a host microorganism, E. coli C600r~m~ to give, clones containing the cDNA insert with variable size as confirmed by the base sequence determination in addition to the colony hybridization and hybrid-arrested translation technique. In vitro recombination of two plasmids obtainable from these clones, pTACR102B6 and pTACR103C2, affords plasmid pCR1001 containing the whole coding sequence for prorennin. On addition of the lac operon of E. coli to pCR1001, plasmid pCR2001 is prepared, which plasmid contains the prorennin cDNA …
