Description générale
The β-Gal Reporter Gene Assay is designed for specifically measuring bacterial β-galactosidase activity. To achieve this, the enzyme reaction is conducted at a pH that is optimized for bacterial β-Gal, but allows no significant endogenous eukaryotic β-galactosidase activity. However, if very high endogenous β-galactosidase activity is found (e.g., with hepatic cells), heat treatment can be performed to ensure the specific determination of the amount of bacterial β-galactosidase that is encoded by the transfected plasmid.
Application
The β-Gal Reporter Gene Assay, chemiluminescent, is used to quantitatively measure β-Gal expression in eukaryotic cells that are transfected with a plasmid bearing the β-Gal-encoding lacZ reporter gene.
Caractéristiques et avantages
- Sensitive: Chemiluminescence technology allows detection of approximately 20 fg β-galactosidase in cell extracts
- High dynamic measuring range: Linear range over four to five orders of magnitude
- Constant light emission: The assay produces a long-lasting light emission instead of a short-peak kinetic
- Safe: No radioactive isotopes are used
- Fast: Approximately 1.5 to 2.5 hours elapse from start to finish
- Convenient: Kit contains all reagents needed, including lysis buffer, protease inhibitors, and a positive control
Conditionnement
1 kit containing 7 components.
Notes préparatoires
