产品介绍 An NF-κB luciferase reporter construct is stably integrated into the genome of CHO-K1 cells. The firefly luciferase gene is controlled by the NF-κB response element located upstream of the TATA promoter. Following activation by stimulants, endogenous NF-κB transcription factors bind to the DNA response elements to induce transcription of the luciferase gene. The NF-κB-luciferase / CHO-K1 cell line is suitable for monitoring the activity of NF-κB transcription factor through luminescence readout.). This cell line responds to human cytokine IL-1β, responds moderately to human TNF_x0004_, and does not respond to human IFN-λ (2 µg/ml). Reducing the amount of serum during incubation period may increase the sensitivity to cytokines. Since CHO-K1 cells do not express endogenous human proteins, this cell line provides an excellent platform to enable exogenous expression of a protein of interest to study its downstream effect on NF-κB signaling.
询价背景介绍 The nuclear factor of activator T cells (NFAT) family of transcription factors plays an important role in immune response. T cell activation through the T cell synapse results in calcium influx. Increased intracellular calcium levels activate the calcium-sensitive phosphatase, calcineurin, which rapidly dephosphorylates the serine-rich region (SRR) and SP-repeats in the amino termini of NFAT proteins. This results in a conformational change that exposes a nuclear localization signal promoting NFAT nuclear import. In the nucleus, NFAT proteins cooperate with other proteins to bind to DNA. 产品介绍 The NFAT Reporter - Jurkat Cell Line contains a firefly luciferase gene under the control of the NFAT response element stably integrated into Jurkat cells. This cell line has been validated for response to thapsigargin, ionomycin, and phorbol 12-myristate 13-acetate (PMA). It is useful as a control cell line for other NFAT reporter cell lines expressing various immune checkpoint receptors.
询价背景介绍 hERG (human ether-a-go-go-related gene) encodes the alpha subunit of a potassium ion channel, Kv11.1. It contains six transmembrane α-helices with a re-entrant "poreloop" between the fifth and the sixth transmembrane helices. This ion channel is best known for its contribution to the electrical activity of the heart that coordinates the heart's beating. When this channel's ability to conduct electrical current across the cell membrane is inhibited or compromised, either by application of drugs or by rare mutations, it can result in a potentially fatal disorder called long QT syndrome. A number of clinically successful drugs in the market exhibit the potential to inhibit hERG, and create a concomitant risk of sudden death as a side-effect, which has made hERG inhibition an important off-target that must be avoided during drug development. 产品介绍 Human ERG channel has been stably expressed in HEK293 cell line and its expression was confirmed by Western blotting. The channel activity of hERG was characterized by a fluorescence-based assay using thallium influx as a surrogate indicator of potassium ion channel activity coupled with a thallium-sensitive fluorescent dye. When hERG-HEK293 cells were pre-loaded with thallium-sensitive dye and stimulated with stimulus buffer containing potassium/thallium, thallium ions flowed through the open hERG channels into the cells and bound the dye, generating a fluorescent signal. The hERG channel activity in hERG-HEK293 cells was blocked by hERG channel blockers, cisapride or dofetilide, causing the fluorescent signal triggered by thallium influx to drop to the basal level.
询价背景介绍 The Hippo pathway regulates cell proliferation and cell death. It is activated by high cell density and cell stress to stop cell proliferation and induce apoptosis. The mammalian Hippo pathway comprises MST kinases and LATS kinases. When the Hippo pathway is activated, MST kinases phosphorylate LATS kinases, which phosphorylate transcriptional co-activators YAP and TAZ. Unphosphorylated YAP and TAZ remain in nucleus and interact with TEAD/TEF transcriptional factors to turn on cell cycle-promoting gene transcription. However, when phosphorylated, YAP and TAZ are recruited from the nucleus to the cytosol, so that the YAP and TAZ-dependent gene transcription is turned off. Dysfunction of the Hippo pathway is frequently detected in human cancer and its down-regulation correlates with the aggressive properties of cancer cells and poor prognosis. 产品介绍 The TEAD Reporter - MCF7 cell line contains the firefly luciferase gene under the control of TEAD responsive elements stably integrated into the human breast cancer cell line, MCF7. Inside the cells, basal unphosphorylated YAP/TAZ remains in the nucleus and induces the constitutive expression of luciferase reporter. The cell line is validated for the inhibition of the expression of luciferase reporter by the activators of the Hippo pathway.

询价产品介绍 The RARβ Reporter (Luc)-HEK293 cell line contains a firefly luciferase gene under the control of retinoic acid response elements stably integrated into HEK293 cells along with full length human RARβ (accession # P10826-2).
询价背景介绍 The dopamine transporter (DAT, SLC6A3) is a membrane-spanning protein that pumps the neurotransmitter dopamine out of the synaptic cleft back into the cytosol, from which other transporters sequester DA and norepinephrine (NE) into vesicles for storage and later release. Dopamine reuptake via DAT provides the primary mechanism through which dopamine is cleared from synapses. DAT is implicated in a number of dopamine-related disorders, including attention deficit hyperactivity disorder, bipolar disorder, clinical depression, and alcoholism. 产品介绍 Recombinant CHOK1 cell line expressing Human sodium-dependent dopamine transporter (DAT), Genbank accession number NM_001044
询价背景介绍 NET is a monoamine transporter responsible for the sodium-chloride (Na+/Cl¯)-dependent reuptake of extracellular norepinephrine (NE), also known as noradrenaline. NET can also reuptake extracellular dopamine (DA). The reuptake of these two neurotransmitters is essential in regulating concentrations in the synaptic cleft. NETs, along with the other monoamine transporters, play a key role in depression and neurodegenerative diseases (NDD) such as Alzheimer's and Parkinson's disease. NET is the target of many antidepressants and recreational drugs. In addition, an overabundance of NET is associated with ADHD. 产品介绍 Recombinant CHOK1 cell line expressing human norepinephrine transporter (NET), Genbank accession number NM_001043.
