The component(s) of serum inhibit C. albicans biofilm formation. A) Biofilm formation of C. albicans ATCC90028 was examined in the presence of different concentrations of heat-inactivated human serum for 24 h at 37°C. a. Scanned image of the XTT reduction assay for quantitation of biofilms. b. Quantitation of biofilms by XTT reduction assay. B) Biofilm formation of C. albicans ATCC90028 was examined in the presence of different concentrations of proteinase K-treated human serum for 24 h at 37°C. (a. Scanned image of the XTT reduction assay for quantitation of biofilms. b. Quantitation of biofilms by XTT reduction assay.) All experiments were done in triplicate with three technical repeats on separate days with similar results. RPMI 1640/HS vs. RPMI 1640, **p < 0.01.
