Fig. 2From: Optimization of the arginase activity assay micromethod for macrophages and seraUse of the non-parametric Mann-Whitney test for intergroup comparisons between activated macrophages vs. control macrophages and HAT sera versus control sera. For the comparison of the two methods, the Kruskal-Wallis test is used for determination of arginase activity in macrophage mouse controls (n = 7) and macrophage mouse T. musculi infected (n = 7)Back to article page
