Transfection-Grade Plasmid Preparation Service

Plasmids are small, circular, double-stranded DNA molecules that are physically separated from the chromosomal DNA and can replicate independently. They are always used by scientists to study genetic engineering. KMD Bioscience is experienced in plasmid extraction and we are constantly striving to improve the quality of the plasmids we offer. Comprehensive plasmid DNA preparation services from microgram to gram-scale are available to support your research.

KMD Bioscience continues to upgrade our DNA preparation platform and transfection-grade plasmid production is provided, which can help achieve highly efficient cell transfection. Plasmids produced by KMD Bioscience are subject to strict quality control to ensure high quality and save your time and energy. Transfection-grade plasmid DNA can be used in research areas such as transfection, protein expression, antibody production, and other research projects.
