| | Homogeneous Time-Resolved Fluorescence (HTRF) Assay |
| Description: | Table B: HTRF assay was carried out using a two-step protocol essentially according to the kit manufacturer's instructions, in 20 μL total volume per well in 384-well plate format (ProxiPlates; PerkinElmer, Fremont, Calif.; catalog #6008280). To each of the experimental wells was transferred 1500 recombinant CHO-K1 cells in 5 μL phosphate buffered saline containing calcium chloride and magnesium chloride (PBS+; Invitrogen, Carlsbad, Calif.; catalog #14040) followed by test compound in 5 μL assay buffer (PBS+ supplemented with 0.2% BSA, 4 μM forskolin and 1 mM IBMX (Sigma-Aldrich, St. Louis, Mo.; catalog #s A8806, F6886 and I5879 respectively). The plate was then incubated at room temperature for 1 h. To each well was then added 5 μL cAMP-d2 conjugate in lysis buffer and 5 μL Cryptate conjugate in lysis buffer according to the kit manufacturer's instructions. The plate was then further incubated at room temperature for 1 h, after which the assay plate was read. |
