ABSTRACT
OBJECTIVE To establish a SNP detection method by DNA piezoelectric biosensor and detect a SNP relative to HBV infection. METHODS To establish a model experiment with synthesis DNA sequences as target and find the lowest sensitivity. After extraction of genome DNA from inpatient blood sample, the SNP sites located in ESR1 gene region in samples were detected by SNP detecting method established. RESULTS The frequency shift of target-A was 416.0?21.5Hz, the frequency shift of target-G was 9.4?5.0Hz. And it could be detected that the lowest sensitivity of target-A was 2?10-11 mol/L. The three genotypes of blood samples, TT, TC and CC, had different frequency shifts, 109.4?13.4Hz, 52.0?11.4Hz and 7.2?4.5Hz, respectively. CONCLUSIONS SNP in blood sample could be detected specifically and sensitively by DNA piezoelectric biosensor.
