Fig. 1. Northern blot hybridization profiles and western blot profiles of CoxI (A) and CoxIV (B) genes and their protein products, respectively, in euthermic (E) and hibernating (H) ground squirrel kidneys. (C) Ratios of scanned band intensities for hibernating versus control values (means ± S.E.M., N=3 separately run northern and western blots; each blot contained RNA or protein, respectively, prepared from separate animals).
