Immunocytochemical localization of tissue kallikrein in brain ventricular epithelium and hypothalamic cell bodies.

Abstract

A specific monoclonal antibody against rat tissue kallikrein was used as the primary antibody for indirect immunoperoxidase staining of rat hypothalamus. Kallikrein was localized in the epithelial cells (ependyma) lining the third ventricle as well as in cell bodies of arcuate, supraoptic, paraventricular, and ventromedial nuclei.
