3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 When the number of cycles of each reaction tube fluorescent signal reaches the set value of the field experienced. 3.2 Recombinant molecule comprising a virus-specific cDNA fragments can be detected as a virus PCR positive control.

4 Method summary

Viral RNA was extracted shellfish sample with a suitable lysis buffer (such as Tri-reagent), and according to sapovirus RNA3 'end Poly (A) structure, connecting with Oligo (dT) 25 magnetic beads specific adsorption sapovirus purified RNA. Water samples of the virus into the Line after enrichment using a suitable method for extracting and purifying viral RNA. Performed using an ordinary fluorescent RT-PCR or real-time RT-PCR. Testing. In this study, by constructing a plasmid standard molecules (plasmid molecule contains one copy of each amplified fragment), determine sapovirus ordinary RT- PCR system for the detection limit of 100 copies, real-time fluorescent RT-PCR system, the detection limit was 10 copies.
