WebMar 3, 2024 · For plasmid isolation, the yield also depends of the size and copy number of the plasmid. Following these protocols the average amount of bifidobacterial chromosomal DNA is 100 μg and 10–30 μg of a plasmid from 5 ml of bacterial culture. 12. Do not mix too much to prevent contamination of chromosomal DNA. WebWhole sonicated chromosomal DNA was also cloned in pUC18 as a population of control fragments. Seventy-one plasmids were labeled with 3H and tested for DNA binding, and the inserts of 28 of them were sequenced. The control plasmid pUC18 was absorbed to competent H. influenzae cells at low levels of 5 to 10% of DNA added.
