Detection limit comparison in the presence of hemolymph, pereiopod, or hepatopancreatic lysate. Direct PCR products were analyzed by (A) agarose gel electrophoresis and (B) capillary electrophoresis. The 140 bp PCR amplification product of the VP28 gene was generated using the WSSV primer pair and 2–250 copies of standard DNA plasmid.
