Fig. 1From: 5-Aminolevulinic acid regulates the immune response in LPS-stimulated RAW 264.7 macrophagesALA induced HO-1 protein expression level without reducing cell viability in RAW264.7 macrophage. a RAW264.7 cells were incubated with or without 1 mM of ALA for 24 h. After treatment, HO-1 protein expression level was analyzed by the Western blotting method. Upper panel, representative Western blot bands. Lower panel, summarized bar graph shows band intensity presented as ratio of HO-1 over GAPDH. Values are means ± SD, n = 2. b The viability of RAW264.7 cells were tested by MTT assay after 24-h incubation in medium containing 1 mM of ALA. Values are means ± SD, n = 3, p values are shown in figuresBack to article page
