Product Information

Storage

Store at -20°C. All components in this kit are stable for at least 12 months when stored at the recommended temperature.

Product Description

The Senescence β-Galactosidase Staining Kit is designed to conveniently provide reagents needed to detect β-galactosidase activity at pH 6, a known characteristic of senescent cells. Papers have published using this kit in both cells and frozen tissue. The kit includes all reagents necessary for this assay.

Background

Limited capacity to replicate is a defining characteristic of most normal cells and culminates in senescence, an arrested state in which the cell remains viable (1). Senescent cells are not stimulated to divide by serum or passage in culture, and senescence invokes a specific cell cycle profile that differs from most damage-induced arrest processes or contact inhibition (2). An enlarged cell size, expression of pH-dependent β-galactosidase activity (3), and an altered pattern of gene expression (4,5) further characterize senescent cells.
