Confirmation of size-distinguishable standardized positive controls under the same RT-PCR conditions as clinical and environmental samples. (A) NoV GI-5 + HRV and environmental sample: lane 1, 100 bp ladder; lane 2, standardized positive control; lane 3, negative control; lane 4, environmental sample. (B) NoV GII-4 + HRV and environmental sample: lane 1, standardized positive control; lane 2, 100 bp ladder; lane 3, negative control; lane 4, negative control; lane 5, environmental sample. (C) NoV GI-6 + HAV and clinical sample: lane 1, 100 bp ladder; lane 2, standardized positive control; lane 3, negative control; lane 4, clinical sample. (D) NoV GII-4 + HAV with clinical sample: lane 1, standardized positive control; lane 2, negative control; lane 3, 100 bp ladder; lane 4, negative control; lane 5, clinical sample.
