Figure Lengend Snippet: ( A ) IDO1 protein and ( B ) gene expression in the vagina of C57BL/6 mice ( n = 4) intravaginally infected with C. albicans . Proteins in vaginal cell lysates (3 dpi) were visualized by western blotting with rabbit polyclonal IDO1 specific antibody. Scanning densitometry was done on a Scion Image apparatus. Western blots out of 2 independent experiments and corresponding pixel density ratio normalized against β-tubulin.
