Abstract
The atrial natriuretic activity of rat heart has been found to exist in multiple forms. One of these factors has been purified to apparent homogeneity by a combination of gel filtration and high pressure liquid chromatography in two different systems and its amino acid composition determined. The purified active peptide is shown to have a molecular weight of approximately 3800. In addition, the vasorelaxant activity of rat atrium has been purified and found to co-chromatograph with the natriuretic activity in all chromatographic systems employed. Thus, the vasorelaxant activity resides in the natriuretic factor. The existence of this new multifunctional peptide implies a higher level of complexity for cardiovascular control of blood volume and pressure.Entities:
