ID: ALA3706332

Type: Binding

Description: Binding Assay: A test compound and 150 uM of a DMSO solution of 5-carboxamide tryptamine (5-CT) were added to a 96-well plate at 2 ul/well and suspended in the incubation buffer, and the HEK293 cells forced to express the human 5-HT5A receptor that were prepared at a concentration of 200 ug/ml were added thereto at 100 ul/well. The cells were incubated for 15 minutes at room temperature, and then a [3H]5-CT solution (3 nM [3H]5-CT, incubation buffer) was added thereto at 100 ul/well.100 ul of the cell solution was separately dispensed into a liquid scintillation vial, and 2 ml of Aquasol II (registered trademark) was added thereto, followed by stirring. Thereafter, the radioactivity thereof was measured using a liquid scintillation counter. The cells were incubated for 60 minutes at 37 C. The reaction mixture was aspirated into a 96-well GF/C filter plate having undergone pretreatment with 0.2% polyethyleneimine, and washed 6 times with an ice-cold 50 mM Tris (pH 7.4).

Cell type: HEK293
