Vasoactive Intestinal Peptide VPAC1 AequoScreen cell line

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.

Detail Information

AequoScreen® Double Transfected Cell Lines: Vasoactive intestinal Peptide, VPAC1 subtype. Human recombinant in CHO-K1 host. Two vials of cryopreserved cells are shipped per order. A detailed technical dossier includes sequence, culture conditions and pharmacological properties of the recombinant receptor. All cell lines are tested for the absence of mycoplasma. Terms and conditions apply. Some products are not available in some 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.
