Mas-related MrgB3 (rat) AequoScreen cell line

false

Our stable recombinant AequoScreen cell lines express a variety of GPCRs which all couple to a calcium response. Upon GPCR stimulation and subsequent calcium binding to the aequorin oxidation of coelenterazine leads to emission of light.

Overview

AequoScreen® Double Transfected Cell Line: Rat Mas-related MrgB3 receptor in aequorin CHO-K1 host cell. We provide two vials of cryopreserved cells (approximately 2.5x10⁶ cells/vial), detailed product information including cell line properties, culture conditions and the pharmacological properties of the recombinant channel in a functional assay. All cell lines are tested for the absence of mycoplasma. Terms and conditions apply. Some of our receptors may be restricted for sale in specified countries. Please inquire at your local sales office for more information.

Features:

Fully automatable and miniaturizable to 1536
Enables reduction in reagents and consumable costs
High signal to background ratio enabling detection of agonists, antagonists and allosteric modulators
Robust assay (Z', CV values, solvent resistance)
Reduces the number of false positives from autofluorescent compounds in screening libraries
Option to work with cells in suspension to increase throughput
Amenable for use with calcium coupled ion channels and tyrosine kinase receptors

The AequoScreen technology is a generic GPCR technology which can be used with Gs, Gi and Gq coupled GPCRs and calcium coupled ion channels. Following receptor stimulation, increases in intracellular calcium enable measurement of the resulting flash luminescence signal.

Application Note

AequoScreen aequorin-encoding Plasmids for performing aequorin luminescent assay starting from non-aequorin cell lines

Aequorin is a photo protein originating from the jellyfish Aequorea Victoria. The apo-enzyme (apoaequorin) is a 21 kD protein, which requires a hydrophobic prosthetic group, coelenterazine, to be converted to aequorin,the active form of the enzyme. This enzyme possesses 3 calcium binding sites which control its activity.

Aequorin bioluminescence assays on MicroBeta2 LumiJET for studying Ca2+-coupled GPCRs and ion channels

Aequorin-based Ca2+ assays represent a new paradigm in drug discovery research for cell-based assays for Ca2+-coupled GPCRs and ion channels. In the aequorin assay, cells co-expressing apoaequorin and the target receptor are first incubated with the co-factor coelenterazinein order to reconstitute the activea equorin enzyme.
