Abstract
The radioimmunoassay of atrial natriuretic factor (ANF) has been applied for determination of immunoreactive ANF (IR-ANF) in rat plasma. Immunoreactive ANF has been extracted from rat plasma by immunoaffinity column on Sepharose-4B anti-ANF or by Vycor glass. The mean concentrations of IR-ANF in ether anesthetized rats were found to be 1.61 +/- 0.14 ng/ml in female and 1.25 +/- 0.21 ng/ml in male rats when extracted on Sepharose-4B anti-ANF, and 1.21 +/- 0.10 ng/ml in females and 1.02 +/- 0.11 ng/ml in males when extracted by Vycor glass. A close linear correlation has been observed between the plasma IR-ANF concentrations in aorta and jugular vein. The described results indicate that atrial cardiocytes secrete atrial natriuretic factor into plasma. The heart is, therefore, an endocrine organ.Entities:
