A cellular senescence detection reagent
SenTraGor™ cell senescence reagent is a detection reagent for lipofuscin, a nondegradable lysosomal marker of cellular senescence.1 It is composed of a Sudan Black B (SBB) derivative conjugated to biotin and can be detected using an anti-biotin antibody. SenTraGor™ cell senescence reagent has been used to detect lipofuscin accumulation in Vero E6 cells infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and primary non-small cell lung cancer (NSCLC) samples as well as soluble lipofuscin in serum from patients with various diseases, including dementia and rheumatoid arthritis.2,3,4
