High Stabilitiy Plasmid Development


  • PCR for repC ligation corroboration


Strains 2, 10 and 11 presented restriction bands different to the rest of the strains (which were false positives). PCR will be performed with the repC speciffic primers Upper_repC (5207) and Low_repC (5208) to corroborate the insertion of repC to pSB1AK3.
