Note: † The reading of plasmid
concentration may varies in the results of multiple measurements, with the approximate range from -5~+15%.
* Sequence verification of full gene insert only applies when bundled with gene synthesis (an insert to be
cloned into a plasmid).
** Percentage of supercoiled plasmid may vary when analyzing with different methods or can be altered due to
shipping conditions.
*** Since densitometry is semi quantitative, the genomic DNA is considered nonvisible if the comparative
intensity of genomic DNA < 15% of plasmid band. Quantitative genomic DNA measurement by qPCR is available with
additional charges.
