Human senescence-associated β-galactosidase (SA-β-gal), the most widely used biomarker of aging, is a valuable tool for assessing the extent of cell 'healthy aging' and potentially predicting the health life span of an individual. Human SA-β-gal is an endogenous lysosomal enzyme expressed from GLB1, the catalytic domain of which is very different from that of E. coli β-gal, a bacterial enzyme encoded by lacZ. However, existing chemical probes for this marker still lack the ability to distinguish human SA-β-gal from β-gal of other s
