Now Available: A Red-Fluorescent cADDis Assay Kit, Manufactured by Montana Molecular, for Measuring cAMP Changes in Live Mammalian Cells

Cyclic AMP (cAMP) is the prototypical second messenger. The major receptor in eukaryotic cells, cAMP-dependent Protein Kinase (PKA), is ubiquitous. cAMP affects many different physiological and biochemical processes, including the activity of kinases. In contrast to the hitherto available green-fluorescent cADDis kit, the red-fluorescent counterpart can be used in combination with green-fluorescent gene constructs, such as GFP, or ion indicators.

Goettingen, Germany, May 19, 2016 --( Cyclic AMP is an essential second messenger for many cellular processes. The messages carried by cAMP are tightly regulated within cells. The red cADDis assay offers an alternative to measurements of cAMP accumulation in cell lysates, because it provides a kinetic measurement of cAMP and can be targeted to specific populations of cells in mixed cultures. The sensor uses a single red-fluorescent protein, so it can be combined with green sensors to measure multiple signals simultaneously.

A protocol has been validated in HEK293, CHO, and NIH 3T3 cells, and is appropriate for live-cell imaging and for screening on automated fluorescence plate readers.

Materials included in the kit:

• Red fluorescent cAMP sensor in BacMam under the control of a CMV promoter (Baculovirus stock).

• Sodium butyrate (Sodium butyrate is added to the culture to maintain BacMam expression. Other HDAC inhibitors may work as well.)

• β2 Adrenergic Receptor BacMam in TNM-FH Insect Culture Medium. (A Gs-coupled receptor provided as a positive control for the purpose of assay optimization.)

• Isoproterenol (Isoproterenol can be used to stimulate Gs signaling through the positive control, the β2 adrenergic receptor.)
