Figure 4From: A pre-S gene chip to detect pre-S deletions in hepatitis B virus large surface antigen as a predictive marker for hepatoma risk in chronic hepatitis B virus carriersResults of the Pre-S Gene Chip analysis. A: The wild-type LHBS gene. B: The pre-S1 mutant LHBS, with nt 3044-3103 of the HBV genome deleted. The signals on probes 6 (nt 3045-3071) and 7 (nt 3074-3103) are negative. C: The pre-S2 mutant LHBS, with nt 3-57 of the HBV genome deleted. The signals on probes 12 (nt 3-32) and 13 (nt 33-62) are negative.Back to article page
