| Description: | Isotope ligand 3H-8-OH-DPAT (67.0 Ci/mmol) was purchased from PerkinElmer Company; 5-HT was purchased from RBI Company; GF/C glass fiber filter paper was purchased from Whatman Company; Tris was imported and divided into aliquots; PPO, POPOP were purchased from Shanghai No. 1 Reagent Factory; lipid-soluble scintillation solution. Beckman LS-6500 Multi-function Liquid Scintillation Counter was used.Procedures(1) The prepared membrane was first applied with appropriate amount of buffer (0.05 M Tris-HCl buffer, containing 0.1% ascorbic acid, 10 um pargyline and 4 mM CaCl2), and homogenizer was used for evenly dispersing. 15 tubes were mixed into a 100 ml container, and appropriate amount of homogenized liquid was added to give 50 ml of membrane suspension, which was reserved for future use.(2) 100 uL of membrane preparation and 100 uL of buffer (0.05 M Tris-HCl buffer, containing 0.1% ascorbic acid, 10 um pargyline and 4 mM CaCl2) were added into each reaction tube. |
