AFB Kinyoun Stain Kit with Methylene Blue Counterstain is a complete cold staining system designed for the detection of acid-fast organisms in clinical and research laboratories. Based on the Kinyoun method, this kit includes a concentrated carbol fuchsin primary stain, acid-alcohol decolorizer, and methylene blue counterstain to provide clear contrast between acid-fast bacteria and background material. Acid-fast organisms appear bright red against a blue background, supporting reliable visualization and differentiation. Suitable for manual staining procedures, the kit is compatible with standard Kinyoun protocols and delivers consistent, reproducible results for routine microbiology applications.
