The sequence of this isolated <em>pre</em>S domain was compared with other <em>pre</em>S domains from the International Gene Bank Database. The identity ranges from 90 to 97%. These results suggested that the HBV strain isolated from Vietnamese patient was an adr subtype.</p>}, number={4}, journal={Academia Journal of Biology}, author={Quyen, Dong Van and Khang, Dinh Duy and Gyu, Yu Gyun}, year={2015}, month={Sep.}, pages={32–36} }
