Fig 6. Fv1 variants in classical inbred strains.

Fig 6

A) The diagrams on the left identify protein sequence differences among the 4 inbred strain alleles. On the right are virus titers for E-MLVs sensitive to Fv1 restriction as determined for NIH3T3 (Fv1n), 129 (Fv1nr), DBA (Fv1d), BALB3T3 (Fv1b), and the wild mouse derived SC-1 (Fv1-). Log10 virus titers were determined by the UV-XC overlay assay; each cell line was tested 3–8 times. B) Inbred strains sequenced for Fv1 alleles. Identical Fv1d sequences were found for substrains DBA/2N and DBA/2J.
