Transfection-Grade Plasmid Preparation Service

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. Plasmids are small, circular, double-stranded DNA molecules that are physically separated from the chromosomal DNA and can replicate independently. And they are always used by scientists to study genetic engineering. Our researchers have rich experience in plasmid extraction; we can provide comprehensive plasmid DNA preparation services from microgram to gram-scale, to meet  different customers’ requirements.

With our upgraded DNA preparation platform, KMD Bioscience offers transfection- grade plasmid production, which can help achieve highly efficient cell transfection. We guarantee you all plasmids we manufactured have strict quality control ensuring the highest quality product will be delivered to our customers. Transfection-grade plasmid DNA can be used in research areas such as transfection, protein expression, antibody production, and other research projects.
