VECTOR MODIFIED BY A SEQUENCE ENCODING A SEQUENCE OF AMINO ACIDS CONTAINED IN A MAMMALIAN PROTEIN HAVING A MEMBRANE RECEPTOR BIOLOGICAL ACTIVITY

摘要

The invention relates to a replicable vector in cultures of unicellular organisms, this vector containing a gene coding for a eukaryotic protein, having a biological activity of a membrane receptor and interacting with a regulatory protein, called G protein, capable of The invention also relates to cellular organisms transformed by the above vectors. / P P It also relates to methods for detecting the ability of a molecule to behave as a ligand to a receptor and a method for studying the affinity of a receptor for a ligand and a kit for detecting the possible affinity of a ligand a ligand to a receptor. / p
