STUDIES ON SULFATION FACTOR (SF) ACTIVITY OF HUMAN SERUM

Abstract

ABSTRACT The relationship of serum sulfation factor (SF) activity to age has been studied in groups of healthy subjects of ages ½, 4, 8, 11, 15, 25 and 70 years. Serum SF activity was present in all subjects. The concentration of serum SF was lowest at ½ and 4 years, rising to comparable peaks at 8 and 15 years of age. The SF activity was the same at ages 11, 25 and 70 years.
