In Auramine O staining, blotches of fluorescence color are caused by which issue?

In Auramine O staining, blotches of fluorescence occur when undissolved particles remain in the dye and settle on the tissue, creating uneven, bright spots under the fluorescence microscope. Filtering the stain removes these particulates, leading to uniform fluorescence. If the stain isn’t filtered, the debris causes those blotches. Heating/cooling or pre-filtering aren’t the root cause of blotchy fluorescence, and water left in tissue would generally dampen or distort the signal rather than produce bright blotches.
