RT Journal Article SR Electronic T1 Intestinal Phosphatase Activity: Acceleration of Increase by Puromycin and Actinomycin JF Science JO Science FD American Association for the Advancement of Science SP 414 OP 416 DO 10.1126/science.144.3617.414 VO 144 IS 3617 A1 Moog, Florence YR 1964 UL http://science.sciencemag.org/content/144/3617/414.abstract AB Alkaline phosphatase activity of the mouse duodenum normally increases 20-fold between 13 and 20 days. Activity at 15 days is raised two to three times above normal by administering actinomycin D, puromycin, or the aminonucleoside of puromycin at 13 or 14 days. Phosphatase activity in the jejunum and kidney are not similarly affected.
