METHOD OF BIOASSAYING YOKKANSAN

摘要

To find out an in vitro bioassay system capable of ensuring improved qualities of yokkansan, it is intended to provide a method of bioassaying yokkansan characterized by comprising treating cells or cell membranes expressing a glutamate receptor competitively with a labeled ligand and yokkansan, measuring the binding activity of the yokkansan, and then evaluating the pharmacological activity of the yokkansan based on the thus obtained data.
