From: Lung fibroblasts from patients with emphysema show markers of senescence in vitro
Southern blot of terminal telomere restriction fragments (derived from of Rsa I/Hinf I digestion of DNA samples) detected by chemiluminescence with a DIG-labeled telomeric probe in combination with anti-DIG-alkaline phosphatase (AP) secondary antibody and CDP-star-AP© substrate. Panel A: Samples from 8 control patients (2 separate gels with molecular weight markers). Panel B: Samples from 7 patients with emphysema (2 separate gels with molecular weight markers)
