title: ANF (Arg 101--Tyr 126) is the peptide secreted by rat atrial cardiocytes in culture.
abstract: The atrial natriuretic factor (ANF) secreted from rat cardiocytes in culture was purified and characterized. The purification procedure involves extraction of ANF by activated Vycor glass, followed by HPLC on C18 mu Bondapak and Vydac columns. The detection of ANF in column eluates was performed by a simple and sensitive radioimmunoassay. The amino acid composition and N-terminal amino acid sequencing appeared to be identical to the Arg 101 - Tyr 126 peptide. The isolated ANF showed biological activity, inhibiting basal and ACTH-stimulating aldosterone secretion from rat zona glomerulosa cells with the same potency as the synthetic peptide.
