Renin concentration after prolonged cold storage of human plasma.
The plasma renin concentration (PRC3.3) measured biologically or radioimmunologically after acid treatment of plasma at pH 3.3, did not change significantly during storage of human plasma at -20 degrees C for 1 year. This is completely in contradiction with the increase in plasma renin activity reported by some authors.
