A monoclonal antibody against a Na(+)-L-glutamate cotransporter from rat brain.

Abstract

A monoclonal mouse IgM antibody (Z8E9) was raised against the Na(+)-L-glutamate cotransporter from rat brain. In a preparation of brain plasma membrane vesicles, Z8E9 binds specifically to a polypeptide with an apparent molecular weight of 70,000 and inhibits Na+ gradient-dependent L-glutamate cotransport (up to 50%) in brain membrane vesicles. In the… (More)
