Abstract

Human renin was extracted according to Helmer's method. In order to purify renin in a form free from angiotensinase, two procedures were used; one was fractionation with ammonium sulfate and the other was pH treatment, acidification to pH 2.9 and alkalinization to pH 9.8. Incubating plasmas with this renin, renin substrate (angiotensinogen) was estimated in 20 normotensive subjects. No quantitative correlation was found between renin and its substrate.
