[Retracted] Antiviral Activity of Plantago asiatica Polysaccharide against Pseudorabies Virus In Vitro

Figure 5

PLP inhibits PRV penetration into PK15 cells. (a) We infected PK15 cells by PRV XJ5 () for a 1 h period at 4°C with PLP, followed by 1 h PLP treatment at diverse doses prior to removing the PLP DMEM and culture in PLP-free DMEM. Protein levels of β-actin and PRV gB were measured through WB at 24 hpi. (b) Viral titers were determined through TCID₅₀. (c) Internalized virus was evaluated by IFA. The error bars indicated SD of 3 separate assays. , .
