Northern Blot analysis of RNA obtained from mammary tumors and normal mammary glands of different strains of mice. The tumor tissues were from RIII/Sa (lane 1), BALB/cfC3H (lane 2), and GR (lane 3) mice. The normal tissues were from WLCO (lane 4), and BALB/c (lane 5) mice. The size of the RNAs were measured in kilobases and are determined by comparing the migration of the RNA in the gel bed to RNA markers. The same filter was used for MMTVrep (Panel A) and jun B (Panel B) hybridizations.
