I am working on biofilm formation of Cryptococcus sp. And Candida sp, i need to know whether XTT assay gives the best result or I can use any alternative protocol for biofilm activity to get good results.
Al alternative for XTT assays, are CTB assays. It's also a metabolic dye, but the read-out is fluorescence instead of absorbance. Metabolic dyes are easy to use for fast screenings. If you want to look at survival, you can consider plating assays (which is more time-consuming.
For all kind of assays on Candida albicans biofilms, you can have a look at publications from Karin Thevissen.
You can as well use crystal violet (CV) staining but that quantifies the biofilm mass rather than measure the biofilm's metabolic activity. Which makes more sense because the cells with a strain's could metabolise XTT differently.
