Table 1. Commonly used SNV-based vectors and packaging cell lines

Vector	Description	Reference
SNV-based avian retroviral vectors
pJD214	SNV-based splicing vector containing ~1 kb of virus sequence	Dougherty and Temin (1987)
pMH105	Bicistronic SNV retroviral vector containing v-rel-IRES-neo	White and Gilmore (1996)
pJD220SVHy	SNV-based vector containing an internal SV40 promoter expressing the hygromycin phosphotransferase B gene (hygro)	Dougherty and Temin (1987)
pIM29	Expresses SNV wild-type SU region of envelope	Martinez and Dornburg (1995a,b)
pRD134	SNV envelope plasmid expressing wild-type proteins	Martinez and Dornburg (1995a,b)
pRD136	SNV packaging construct expressing wild-type gag-pol	Martinez and Dornburg (1995a,b)
pZP32	SNV packaging construct with mutation in matrix region	Parveen et al. (2000, 2003)
pZP36	SNV-based retroviral vector used for generation of viral particles expressing LacZ	Parveen et al. (2003)
pEM12 and 13	Bicistronic vectors expressing anti-HIV-1 genes	Marusich et al. (2005)

Packaging cell lines for SNV-based vectors
D17	Canine osteosarcoma cell line, permissive to infection by SNV, REV-A, and murine leukemia virus^a	Riggs et al. (1974)
C3A2	A derivative of D17 cell line expressing REV-A gag-pol and env	Watanabe and Temin (1983)
DSH134G	SNV-based packaging cell line	Martinez and Dornburg (1995a,b)
DSH-cxl	SNV-based packaging cell line with β-gal as marker

^aREV-A and SNV are >90% homologous. REV-A proteins have also been reported to package SNV-derived vectors with high efficiency (Yin and Hu 1997).
