Research Grade Plasmid Preparation


Plasmid end products prepared through PackGene’s Plasmid Extraction service are viable for transfection application across the discovery and preclinical research phases.

The quality of plasmid will have a direct impact on the experimental outcome of downstream applications. With years of experience and process optimization PackGene has developed a robust protocol for plasmid preparation services accommodating to both small research labs to biotech and pharmaceutical companies. Choose from our high-quality plasmid from 100ug to 1000mg and up, with high homogeneity and ultra-low endotoxin level (<10EU/mg).
