Identification of plasma inactive renin as prorenin with a site-directed antibody.
A sequence-specific antibody that recognizes a portion of the prosegment of human renin precursor was raised and used to provide direct evidence that plasma inactive renin contains the prosequence of renal renin and is therefore probably prorenin rather than an inactivated form of previously active renin. The information may help not only to resolve a major controversy concerning the nature of inactive renin in human plasma but also to elucidate its exact physiological role.
