Assay Method Information

Assay Name:  Receptor Binding Assay
Description:  Materials for the Receptor Binding AssayIsotope ligand [3H]-Ketanserin (67.0 Ci/mmol) was purchased from PerkinElmer Company; Methysergide 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: 6.05 g of Tris was dissolved in 1000 ml of double-distilled water, and concentrated HCl was used to adjust to pH 7.5), 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.
