Description

Bridge-It® Cyclic AMP (cAMP) Assays – Selectivity, Sensitivity and Performance Characteristics

The Bridge-It® Cyclic AMP (cAMP) assay is highly specific. ATP, AMP, and cGMP have all been tested for selectivity using the cAMP assay. No response was detected using the Bridge-It® cAMP assay with any of these compounds within the concentration range that would be expected to occur in “real life” samples (i.e., millimolar range for AMP and ATP, and micromolar range for cGMP). The sensitivity and performance characteristics of the Bridge-It®cAMP designer and the Bridge-It® all in one assay products are presented in the following Table and Figures.

The Bridge-It® cAMP all in one assay allows for the stimulation and measurement of cAMP in adherent monolayer cells attached to the wells of a tissue culture microplate. In the following example, HEK 293 cells were trypsinized and plated into the wells of a 96-well polystyrene tissue culture microplate at a density of 25,000 cells per well in 50 µl of culture media. The cells were allowed to attach to the bottom of the wells overnight. The media was removed the next day and the wells were washed with a buffered saline solution. The wash buffer was then removed and replaced with 50 µl of KRB-IBMX buffer. For stimulation, 1 µl of forskolin at different concentrations was added to each well and incubated and rotated gently for 15 minutes at ~25ºC. To quantify cAMP in each well, the forskolin buffer solution was removed, 100 µl of the all in one Assay Solution was added to each well, and the microplate was incubated for 30 minutes at ~25ºC with rotation. The well contents were then transferred into a black 96-well microplate and the fluorescent signal was read using the settings for fluorescein (~485 nm excitation, ~540 nm emission).
