The nucleic acid vaccines development process is mainly divided into the following steps: isolation and screening of pathogenic genes, sequencing of pathogenic genes, targeted cloning of antigen genes, the introduction of recombinant genes into recipient cells, screening and identification of recombinant genes, and large-scale antigen gene synthesis. As we all know, time is extremely precious for vaccines development, and every second of delay means that more people who have not been vaccinated will die. The htDNA-chip® technology platform can greatly shorten the vaccine development time and also ensure accuracy.
