Preclinical-Grade Plasmid DNA Preparation Service

KMD Bioscience has been working on molecular biology research for many years. Plasmid vector is a powerful tool for genetic engineering. The quality of DNA obtained is a critical factor for genetic experimentation. Our researchers have rich experience in plasmid extraction; we can provide comprehensive plasmid DNA preparation services from microgram to gram-scale in order to meet different customers' requirements.

With our upgraded DNA preparation platform, KMD Bioscience offers preclinical-grade plasmid production with the most comprehensive and stringent quality specifications and analysis for preclinical project needs. We guarantee that all plasmids we produce are subject to strict quality control to ensure that the highest quality products will be delivered to our customers. Preclinical-grade plasmid DNA can be used in preclinical research such as vivo animal studies, from mice to non-human primates, gene therapy, cell therapy, vaccine research, etc.
