p70 expression analysis. (A) Northern blots containing poly(A)⁺ RNA from multiple murine tissues were probed with a p70 cDNA probe (upper panel) or a glyceraldehyde-3-phosphate dehydrogenase (GAPDH) probe (lower panel). Positions of p70 mRNA and GAPDH mRNA are indicated, as are positions of standard markers, in kilobases. (B) Lysates prepared from the indicated cell lines were subjected to immunoprecipitation/Western blot analysis utilizing anti-p70 peptide antibody. (C) Lysates prepared from the indicated murine tissues were subjected to immunoprecipitation/Western blot analysis utilizing anti-p70 peptide antibody.
