Plasmid DNA Preparation Services

KMD Bioscience has been striking on recombinant protein expression and antibody development for many years, and we understand the need for impurities, to produce clean, reproducible results. Plasmid vector is a powerful tool for genetic engineering. The quality of DNA obtained is critical factor for genetic experimentation. We can provide comprehensive plasmid DNA preparation services from microgram to gram-scale to meet research institutes and biotechnology industries customers’  requirements.

With our upgraded DNA preparation platform, KMD Bioscience offers several different research-grade and preclinical grade plasmid production. We have rich experience in plasmid extraction, we guarantee that the highest quality product will be delivered to our customers. A variety of our packages are designed to support diverse downstream applications such as transfection, antibody preparation, vaccine, and gene-therapy research, etc.
