Hi An easy fix is to PCR amplify your low copy number plasmid (modern polymerases have no issues amplifying up to 20 kB if you have a largeish vector) and then sequence the product. Alternatively you can amplify just a portion of interest, of course (you said sequence the plasmid so I went with yo

The pACYC vectors (probably your p15ori plasmid) is said to have a copy number of ~10 copies per cell while your other plasmid is likely in the hundreds - see: https://blog.addgene.org/plasmid-101-origin-of-replication The protein expression level from the lower copy number plasmid is usually

Hi All, I have two constructs having different ori, p15ori and M13 ori, different promoters araBAD promoter and LacI, and different antibiotic resistance chloramphenicol and Ampicillin respectively. I am managed to get the transformants and getting the expected result after blunt digestion with th
