General description
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.
Features and Benefits
- 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
Packaging
1 kit containing 7 components.
Preparation Note
Storage conditions (working solution): Substrate Reagent (solution 1) is stable at least for 24 h at 2 to 8 °C.
Initation Reagent (solution 2) is stable for at least 4 weeks when stored at 2 to 8 °C.
Lysis Reagent, 1x (solution 3) Lysis reagent without protease inhibitors is stable at
-15 to -25 °C or for 3 months at 2 to 8 °C. Lysis reagent containing protease inhibitors is stable for one week when stored frozen at -15 to -25 °C.
Positive Control (solution 4) The reconstituted enzyme solution is stable for 1 week at 2 to 8 °C. When stored frozen in aliquots at -15 to -25 °C the enzyme is stable for 3 months. Avoid multiple freezing and thawing.

The homeodomain transcription factor Hoxa2 interacts with the RING-finger type E3 ubiquitin ligase RCHY1 and induces its proteasomal degradation. In this work, we dissected this non-transcriptional activity of Hoxa2 at the molecular level. The Hoxa2-mediated decay of RCHY1 involves both

Regulation of transcription factor activity relies on molecular interactions or enzymatic modifications which influence their interaction with DNA cis-regulatory sequences, their transcriptional activation or repression, and stability or intracellular distribution of these proteins. Regarding the well-conserved Hox protein family, a
