Description: The GloResponse Luciferase Reporter Cell Lines contain
optimized, state-of-the-art luciferase reporter technology integrated into a
cell line. This allows the rapid development of a reporter assay based on the
pathway of interest regulating the luciferase gene. Assays configured using the
GloResponse Cell Lines are amenable for high-throughput screening. These
assays typically have greater response dynamics (fold of induction) than other
assay formats and good quality as indicated by the high Z´ values.
GloResponse Cell Lines were developed to study a variety of signaling
pathways. Activators of these pathways may be native to the HEK293 cell line.
Activity of non-native activators can be studied after they have been introduced
by transfection.
GPCRs regulate a wide-range of biological functions and are one of the most
important target classes for drug discovery. GPCR signaling pathways can be
categorized into three classes based on the G protein α-subunit involved: Gs,
Gi/o and Gq. The GloResponse CRE-luc2P HEK293 Cell Line can be used to
study and configure screening assays for Gs- and Gi/o-coupled GPCRs, which
signal through cAMP and the cAMP Response Element (CRE). For Gq-coupled
GPCRs, which signal through calcium ion release and activate the Nuclear
Factor of Activated T-Cells response element (NFAT-RE), the GloResponse
NFAT-RE-luc2P HEK293 Cell Line should be used.
NF-κB-REs are the DNA binding sequences for the NF-κB transcription factor
complex, which is responsible for regulating inflammation, immune response,
cell growth and apoptosis. The GloResponse NF-κB-RE-luc2P HEK293 Cell
Line is designed for rapid and convenient analysis of any cellular response that
results in modulation of NF-κB activities.
The GloResponse 9XGAL4UAS-luc2P HEK293 Cell Line contains nine
repeats of GAL4 UAS (Upstream Activator Sequence) driving the transcription
of the luciferase reporter gene luc2P in response to binding of a fusion protein
containing the GAL4 DNA Binding Domain, such as the Estrogen Receptor
Ligand Binding Domain in pBIND-ERα Vector (Cat.# E1390) when activated by
a ligand. This makes the cell line suitable for the study of nuclear receptors or
can be used to study other types of protein:protein and protein:DNA
interactions. The GAL4 DNA Binding Domain partner must be introduced to this
cell line by transfection or other similar techniques.
The GloResponse Cell Lines were generated by clonal selection of HEK293
cells stably transfected with pGL4-based vectors carrying specific response
elements for the pathway of interest. These cell lines incorporate the
improvements developed for the pGL4 family of reporter vectors for enhanced
performance. The destabilized luc2P luciferase reporter is used for improved
responsiveness to transcriptional dynamics. The luc2P gene is codon optimized
for enhanced expression in mammalian cells, and the pGL4 plasmid backbone
was engineered to reduce background reporter expression. The result is a cell
line with very high induction levels when the pathway of interest is activated.
Features:
• Convenient: Prebuilt, optimized luciferase reporter cell lines.
• Robust: Large assay window provided by high levels of induction and low
background expression.
• Faster Results: Improved responsiveness to transcriptional dynamics with
destabilized luciferase.
Storage Conditions: Place frozen cells in storage at less than or equal to
–140°C (mechanical deep freeze or vapor phase liquid nitrogen) until you are
ready to thaw and propagate them. We strongly recommend that the cells are
propagated, using the provided procedure, as soon as possible. This will ensure
the optimal cell viability and assay performance.

Ranking compound potency and detection of DRD1 partial agonists. A
GloResponse CRE-luc2P clone stably expressing dopamine receptor D1 was
plated at 10,000 cells/well in a 96-well plate. Each agonist was serially diluted
1:2, then added to wells in replicates of four, beginning with 50μM. Cells
were incubated with agonist for four hours, harvested and analyzed using the
Dual-Glo Luciferase Assay System (Cat.# E2920). Luciferase activity was
measured on the GloMax ® 96 Microplate Luminometer (Cat.# E6501).
