Novel receptor

摘要

A receptor in substantially pure form obtainable from rat forebrain tissue which is characterized in that; a) compound A binds to it with a Kd of 40 nM for rat forebrain tissue, b) compound A binds to it with a Bmax of 220 pmol/g protein for rat forebrain tissue c) compound B binds to it with a Kd of 2 nM for rat forebrain tissue d) compound B binds to it with a Bmax of 220 pmol/g protein for rat forebrain tissue; and homologous receptors from other sources sharing at least 85% homology with the rat forebrain tissue.
