SAFB1 protein expression in tissues from SAFB1+/+ and SAFB1+/- mice. A) A representative immunoblot using lysates from different tissues, and antibodies, as indicated. β-actin was used as a loading control. Blots are shown are from mice on a C57Bl/6J × 129/Sv genetic background, but is also representative of difference observed in mice on a BALB/c background. B) Percentage of SAFB1 protein levels in SAFB1+/- tissues, corrected for b-actin levels, relative to protein levels in SAFB1+/+ mice.
