Congo red stock solution is a dye solution primarily used in histology and microbiology for staining purposes. It is particularly known for its ability to bind to amyloid proteins, making it useful in the diagnosis of amyloidosis. The solution is typically prepared by dissolving Congo red powder in a suitable buffer or solvent, such as distilled water or ethanol, to achieve a specific concentration. In addition to its staining applications, Congo red has also been used in various biochemical assays.

Congo red is primarily used as a negative stain, as it binds to the polysaccharides in the cell wall of certain bacteria, resulting in a red appearance against a blue background. Crystal violet, on the other hand, is commonly used for positive staining; it is the primary stain in the Gram staining procedure, where it stains the peptidoglycan layer of Gram-positive bacteria, turning them purple. Thus, Congo red is not suitable for positive staining, while crystal violet is not typically used for negative staining.
