Data Sheet

Normal mammalian cells divide for a limited number of population doublings and eventually enter an arrested state in which the cells remain alive, but do not proliferate in response to mitogens, and assume a characteristic enlarged, flattened morphology. This process, termed senescence, is thought to be a tumor suppressive mechanism and underlying cause of aging. Senescence-associated beta-galactosidase (SA- beta-gal) is a widely used biochemical maker for assessing senescence in cultured cells.

Assay Characteristics

Innoprot Cell Senescence Assay provides an easy-to-use method to detect SA- beta-gal by staining cells with 5-bromo-4-chloro-3-indolyl- beta-D-galactopyranoside (X-gal) at pH 6.0, a pH condition that suppress lysosomal beta-galactosidase activity sufficiently to ensure that nonsenescent cells remain unstained.
