Figure 2From: A direct real-time polymerase chain reaction assay for rapid high-throughput detection of highly pathogenic North American porcine reproductive and respiratory syndrome virus in China without RNA purificationSensitivity of the dRT-PCR assay. The HP-PRRSV-infected cell supernatant was 10-fold serially diluted with PRRSV-negative serum. Viral titers ranged from 104.8 TCID50/μL to 100.8 TCID50/μL. Each diluted sample was assayed in triplicate.Back to article page
