Arginase activity in activated macrophages.

BMMΦ were derived from pre-pubertal (3–4 weeks), adult (10 weeks) and older (40 weeks) BALB/c mice and differentiated into AAMΦ with 20 U/ml IL-4 and arginase activity was measured by enzymatic assay.Data show the results of one representative experiment out of two independent experiments.本研究所用骨髓来源巨噬细胞（Bone Marrow-derived Macrophages, BMMΦ）分别分离自青春期前（3~4周龄）、成年（10周龄）及老年（40周龄）的BALB/c小鼠，以20 U/ml白细胞介素4（Interleukin-4, IL-4）诱导其分化为交替激活巨噬细胞（Alternatively activated macrophages, AAMΦ），并通过酶学法检测精氨酸酶活性。本次呈现的数据为两次独立实验中的一次代表性实验结果。
