  • Detection of human hepatitis B virus surface antigen mutants by specific amplification and its application on gene chip
    Patent number: 6759193
    Abstract: Novel DNA probe sequences for detection, by polymerase chain reaction, of human hepatitis B virus surface antigen mutant 145 (Glycine to Arginine) from serum samples. As a direct application, these specific DNA probes are immobilized on solid glass supports (gene chip) for detection of human hepatitis B virus surface antigen mutant 145 (Glycine to Arginine) by fluorescence.
    Type: Grant
    Filed: July 28, 1999
    Date of Patent: July 6, 2004
    Assignee: The Government of the Republic of Singapore
    Inventors: Chong-Jin Oon, Wei-Ning Chen, Ai-Lin Leong, Shiuan Koh
