Influence of arsenic concentration on PCR performance. DNA template from fresh tissue sample Gglagla8. Arsenic concentrations (μg/μl): lanes 1-8: 0 - 4.6 - 4.8 - 5.0 - 5.2 - 5.4 - 6.0 - control sample (without DNA or arsenic). Signal intensity decreases with increasing arsenic concentration and breaks down from sample 6 (5.4 μg/μl).
