Virus PEDV TGEV RV PRRSV CSFV PCV2 PRV
Mean OD450 values 1.086 0.113 0.111 0.112 0.1 0.101 0.11
PEDV-N concentration(μg/L) 26.45 −0.53 −0.64 −0.59 −1.1 −0.94 −0.65

The different pathogens were inactivated by treatment with 1% Triton X-100 and 0.3% TNBP for 2 h at RT, and then detected by the DAS-qELISA at optimum conditions.
