Figure 5From: Impairment of alternative splice sites defining a novel gammaretroviral exon within gagmodifies the oncogenic properties of Akv murine leukemia virusNorthern blot hybridizations with an ecotropic specific env probe and a gag probe of RNA isolated from NIH 3T3 cells chronically infected with the viruses listed above each lane. The sizes of the full-length transcript (unspliced) and the single-spliced env transcript are indicated at the left. The arrow indicates splice product C. For verification of integrity and concentration of the loaded RNA, the original ethidium bromide stained agarose gel exposing 18S and 28S rRNAs is shown below.Back to article page
