Frozen Cells validated for calcium testing: Secretin receptor, human recombinant, in CHO-K1 host cell. We provide one vial of frozen cells (10 million cells/vial). Some of our Frozen cells may be restricted for sale in specified countries. Please inquire at your local sales office for more information. You are authorized to utilize these frozen cell preparations one time only. Any attempt to transfer, re-use, or propagate these cells is expressly unauthorized and a violation of the product terms and conditions of sale.
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.
The frozen cells approach to functional testing consists in the dissociation of cell culture from testing. That means that we will culture the cells and freeze them with an optimized protocol to stop all replication. These cells are then stored in liquid nitrogen or simply in a -80°C freezer, thawed and used directly in a functional, cellular GPCR test with previously validated performance.

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-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.
PerkinElmer’s validated, ready-to-use AequoZen™or cAMPZen™ frozen, irradiated cells make it easier for you to perform functional testing of GPCRs. Just thaw and use! Reliable, convenient AequoZen cells for aequorin calcium testing or cAMPZen cells for cAMP testing let you get the testing done. So you can concentrate on results.
FroZen, -irradiated cells, are a well established product, that can be ordered as a consumable, and readily used to perform Aequorin functional assays (AequoZen) or cAMP assays (cAMPZen). While, for the G s–coupled receptors, an increase of cAMP is detected in such an assay, for G i-coupled receptors an inhibition of the forskolin-stimulated level of, cAMP is detected.
