title: Evidence against inhibition of the renin-angiotensinogen reaction by des-angiotensin substrate in the rat.
abstract: 1. The possible inhibitory effect of des-angiotensin I substrate on the renin-substrate reaction was studied. For this purpose rat angiotensinogen was purified 50-fool from plasma of nephrectomized rats. Des-angiotensin substrate was prepared from the purified angiotensinogen preparation by reaction with immobilized hog renin (coupled to Sepharose). 2. In kinetic experiments it was found that desangiotensin I substrate in concentrations of 0-225 and 0-45 micronmol/l has no influence on the reaction between rat renin and rat angiotensinogen.
