From: DNA aptamers targeting glycoprotein D enable specific detection of pseudorabies virus (PRV)
Specific binding of DNA aptamers to PRV particles. A Binding of DNA aptamers to PRV, PEDV, and PRRSV viral particles was detected via ELISA. B Colocalization of FAM-labeled Apt-gD-2 with PRV-QXX-infected PK15 cells. Viral gB protein was detected via a mouse anti-gB mAb and Alexa Fluor® 594-labeled secondary antibody. Nuclei were stained with DAPI. A virus-free negative control was included. Images were captured via confocal microscopy
