Co-existence of CRF and vasopressin immunoreactivity in parvocellular paraventricular neurons of rat hypothalamus.

abstract：:The study was undertaken to investigate the oxidation and reduction of cholecystokinin (CCK) both as pure standards and as endogenous porcine peptides. Furthermore an attempt was made to prevent oxidation of the endogenous porcine peptides in the extraction procedure. CCK-8 and CCK-33 standards were always oxidized in...
