Quintara Biosciences

Plasmid DNA Maxiprep

QuintaraBio provides high quantity, large scale transfection grade plasmid DNA from bacterial cultures. Using streamlined production workflow and proprietary technology, we deliver purified plasmid DNA in various quantity packages within 3-5 days. We accept most sample formats; e.g. plasmid DNA, agar plates, stripes, glycerol stock, and liquid cultures. Using Macherey-Nagel NecleoBond®Xtra Endofree Kits - the gold standard for this procedure with endotoxin removal technology to product high standard endotxon-free plasmid DNA.

QuintaraBio's large-scale plasmid DNA service is suitable for customers who work with direct transfection with mammalian cell lines or stem cells which undergoes rigorous quality control steps. With our guaranteed endotoxin free standard (<1 EU/mg), you can achieve a high expression level of the plasmid with minimal concern about the cell toxicity.

Our turnaround time is 50% faster and the plasmid is 50x cleaner than other providers using magnetic beads and cheaper reagents.
