Figure 2From: Quantitative digital in situ senescence-associated β-galactosidase assayBGAVs change with increasing population doublings. The BGAVs obtained at pH 6.0 at progressively increasing PDs of both FSE and BJ fibroblast cells. FSE cells were analyzed between PD 34-58 and BJ cells were analyzed between PD 57-65. Both cell types were stained for SABG activity at weekly intervals.Back to article page
