Quality Control
Every DNA prep is verified by next-generation sequencing, confirming plasmid identity, sequence integrity, and absence of DNA contaminants. Concentration is confirmed to be within ±2.5% of the stated concentration.
Our production process has been validated to consistently yield endotoxin levels below 1.0 EU/μg. Individual lots are not tested for endotoxin.
