The expression and purification of plant-produced WNV-EDIII-SC (25 kDa). (A) Immunoblot of crude leaf extracts (4 dpi) of WNV-EDIII-SC co-infiltrated with either CNX or CRT. Lanes were loaded with 25 μg TSP each for direct comparison and WNV-EDIII-SC protein was detected with in-house-produced anti-WNV-EDIII serum. (B) Coomassie blue-stained SDS-PAGE of eluted fractions of WNV-EDIII-SC following pH precipitation and nickel-affinity chromatography. pTRAkc: pTRAkc-ERH empty plant-expression vector. CNX, calnexin; CRT, calreticulin; F, fraction.
