Plasmid DNA is a circular, self-replicating molecule widely used as a vector in gene therapy and vaccine production. It serves as a raw material for viral vector construction (LV, AAV), a transcription template for mRNA vaccines, or the final product for DNA vaccines.
Yaohai Bio-Pharma has established GMP-compliant platforms for circular and linear plasmid production, offering plasmid manufacturing services spanning from preclinical and clinical stages to commercial production. This enables cell and gene therapy innovators to accelerate R&D and commercialization with high-efficiency support.
