Senescence-like phenotype in post-mitotic cells of mice entering middle age
Figure 5. pH-dependent (pH 4 to pH 7) β-gal activity in frozen sections of 9 months old C57/Bl6J mouse pancreas. Nuclear Fast Red was used for counterstaining. At pH 6, specific for SA-β-gal, bluish color from β-gal activity is evident specifically in pancreatic islets. Representative images from 3 different mice are shown.
