Propagation and Assay of BK Virus, England in 1971 (.). Seroprevalence studies have shown that BK infection is widespread in children throughout the world, and the virus thereafter persists latently in the kidney for life. Immunosuppression can lead to reactivation of the virus and prolonged viruria (.). Although in immunocompetent有助于 发表于 2025-3-24 08:51:25

Methods for Studying Interactions Between Simian Virus 40 T-Antigen and the Viral Origin of Replicamajor advantage of this system is that, with the exception of one viral protein, termed T-antigen (T-ag), all of the proteins required for DNA replication are supplied by cells that are permissive for SV40 replication (.). Because the virus depends on host proteins for replication (.), the SV40 syst馆长 发表于 2025-3-24 17:08:11
Quantitation and Structural Analysis of SV40 RNAs, the late unit, which is expressed at a significant level only after the onset of viral DNA replication (.). The early genes encode the viral regulatory proteins, small, and large T-antigens. These proteins play roles in replication of the viral genome and transcriptional transactivation of the latecorpuscle 发表于 2025-3-24 22:04:03

Production of SV40 Proteins in Insect Cells and In Vitro Packaging of Virions and Pseudovirions,tors. Although prokaryotic expression systems provide higher yields and are technically simpler to use, obtaining biologically active eukaryotic proteins in these systems can be problematic. Posttranslational modifications such as glycosylation and phosphorylation do not occur in prokaryotic systems
