beta galactosidase assay,
A simple assay for DNA transfection by incubation of the cells in culture dishes with substrates for beta-galactosidase.
Although the Escherichia coli lacZ gene, encoding β-galactosidase (β-gal), can be used as a standard reporter for monitoring the strength of a promoter or enhancer in a transient or stable transfection assay, it is predominantly used as an internal .The β-Gal Assay Kit provides the reagents required to quickly measure the levels of active β-galactosidase expressed in cells transfected with plasmids expressing the lacZ gene. lacZ is a bacterial gene often used as a reporter construct in eukaryotic transfection experiments.
β-Galactosidase is an exoglycosidase which hydrolyzes the β- glycosidic bond formed between a galactose and its organic moiety. It may also cleave fucosides and arabinosides but at a much lower rate. It is an essential enzyme in the human body. Deficiencies in the protein can result in galactosialidosis or Morquio B syndrome.beta galactosidase assayβ-Galactosidase is an exoglycosidase which hydrolyzes the β- glycosidic bond formed between a galactose and its organic moiety.

Recently, the β-galactosidase assay has become a key component in the development of assays and biosensors for the detection of enterobacteria and E. coli in water quality monitoring. The assay has often performed below its maximum potential, mainly due to a poor choice of conditions.This enzyme facilitates growth on carbon sources like lactose by cleaving it into a molecule of glucose and a molecule of galactose which the cells can catabolize and grow on. In the assay described above, the substrate o-nitrophenyl-β-D-galactopyraniside (ONPG) is .beta galactosidase assay SenescenceOverall, the single-step β-galactosidase assay yields both consistent and accurate results over the range of cell densities and LacZ levels typically tested with a standard β-galactosidase assay and is a suitable faster and safer alternative to the traditional method (or current methods used).High levels of senescence-associated β-galactosidase (SA-β-gal) can be found in cancer and benign lesions of various localizations making the enzyme a highly promising diagnostic marker for visualization of tumor margins and metastases. These findings facilitate the research of therapy induced senescence as a promising therapeutic strategy.SenescenceHigh levels of senescence-associated β-galactosidase (SA-β-gal) can be found in cancer and benign lesions of various localizations making the enzyme a highly promising diagnostic marker for visualization of tumor margins and metastases.
