Senescence Detection Kit

Кат. номер

QIA117-1KIT

QIA117-1KITCN

Useful for the histochemical detection of senescent cells. The failure of cells to become senescent may lead to tumor progression. Higher levels of β-Galactosidase is considered as a good marker for senescent cells. The mechanism of this is believed to be due to the increased lysosomal content of senescent cells, resulting in an increase of the lysosomal enzyme β-galactosidase. Cells can be observed using microscope.
Senescence is thought to be a tumor suppressive mechanism and an underlying cause of aging. It represents an arrested state in which the cells remain viable, but not stimulated to divide by serum or by passage in culture. Senescent cells display an increase in cell size, pH-dependent expression of β-galactosidase (β-Gal) activity, and altered patterns of gene expression.

The Calbiochem® Senescence Detection Kit is useful for the histochemical detection of senescent cells. The failure of cells to become senescent may lead to tumor progression. The mechanism of this is believed to be the increased lysosomal content of senescent cells resulting in an increase of the lysosomal enzyme -galactosidase.
• PBS: Prepare a 1X PBS solution (not provided). Use at least 3 ml per well.• X-gal: Dissolve 20 mg X-gal in 1 ml of DMF (N-N-dimethylformamide, not provided) to prepare a 20X stock solution. Aliquot and freeze (-20°) the unused X-gal solution. This stock solution is stable for up to 1 month at -20°C (protect from light). Always store X-gal in a polypropylene or glass container. Do not use polystyrene.• Staining Solution Mix: While cells are incubating in Fixative Solution (step 2 below), prepare Staining Solution Mix in a polypropylene plastic tube by adding 470 µl of Staining Solution, 5 µl Staining Supplement, and 25 µl of 20 mg/ml X-gal in DMF.
Upon arrival store the entire contents of the kit at -20°C.
