Figure 2From: Construction and characterization of an infectious replication competent clone of porcine endogenous retrovirus from Chinese miniature pigsPCR analysis of cellular DNA from HEK293 cells infected with PERV derived from WZS-PERV(2), and replication kinetics of PERV derived from the clone. A. PCR products of genomic DNA from HEK293 cells infected with PERV derived from the WZS-PERV(2) clone using the pol and human β-actin genes for 51 days. B. Numbers of PERV particles from the supernatants (per ml) during 51 days.Back to article page
