Although the sample has been verified before, why the sequencing result would show an empty plasmid with inserted fragments?

August 13, 2019 12:19

Sequencing is the best proof of the sample. This might be due to:
1) The loss of insert fragments may occur during culturing, which cannot be verified except by sequencing.
2) The clones provided are false positive clones.
