      GMP mRNA Production Process
      GMP mRNA production process
      At PackGene and Kudo Biotechnology, we are committed to delivering the highest quality GMP mRNA production process. Our process starts with GMP plasmid DNA manufacturing, which includes the creation of an E. coli strain cell bank, fermentation, plasmid DNA purification, and QC release to ensure that the DNA is of the highest quality.

      Next, we move on to mRNA transcription and purification, where we linearize the pDNA and perform in-vitro transcription, capping, dsRNA removal, bulk purification, and QC release to ensure that the mRNA is pure and free from contaminants.

      Comprehensive Analytical Panel
      Our comprehensive analytical panel allows for customized in-process control, release testing, and stability studies for plasmid, mRNA, and LNP. This enables us to tailor our approach to meet the specific needs of your project and ensure that the final product is of the highest quality.
