Popis: | Extract: The enzymatic activity hydrolyzing γ-glutamyl-β-naphthylamide (γ-glutamyltranspeptidase, GGTP) was studied in the small intestine of human adults and fetuses. Surgical biopsies taken from the proximal jejunum approximately 10 cm from the ligament of Treitz served as the source of the enzyme for adult subjects. The entire small bowel was obtained from fetuses of different ages and divided into three thirds for enzymatic assay. All samples were frozen immediately and used within 1–4 months. It was shown that enzymatic activities stored at −20° are stable for that period. |
