About Auramine for Microscopy
Auramine is known to be diarylmethane dye which acts as a version of Schiff reagent and its crystals appear to be yellow in color in their pure form. It is soluble in water and ethanol. Being a fluorescent stain in nature, our offered Auramine plays a crucial role in the process of microscopy with its staining capabilities of detecting acid-fast bacteria called Mycobaterium. During microscopy, possibility of artifacts can be minimized by the counter stain potassium permanganate. Thus, the cells viewed appear to be reddish orange or bright yellow in color under ultraviolet light. When it combines with Rhodamine, mycolic acids present in cell wall of various organisms helps in providing resistance against de-colorization with the help of acid-alcohol.

FAQ's of Auramine for Microscopy:
Q: How should Auramine O be stored for optimal shelf life?
A: Store Auramine O in a cool, dry place away from direct light. This ensures it remains stable and maintains its effectiveness throughout its 36-month shelf life.
Q: What is the recommended concentration of Auramine O for staining?
A: For microscopy and fluorescent staining, dilute Auramine O to a working solution in the range of 0.1-1% (w/v). Prepare fresh solutions as needed to guarantee optimal staining results.
Q: When is Auramine O used in laboratory microscopy?
A: Auramine O is typically used during microscopic examination and acid-fast staining procedures, particularly for detecting mycobacteria and certain fungi in clinical and research laboratories.
Q: Where can Auramine O be sourced and in what packaging sizes?
A: Auramine O is available from dealers, exporters, manufacturers, retailers, suppliers, and traders across India. It is supplied in 25 g, 100 g, and 500 g bottles for laboratory use.
Q: What precautions should be taken while using Auramine O?
A: As Auramine O is classified as an irritant, you should handle it with gloves, protective clothing, and in a well-ventilated area. Avoid inhalation and skin contact to maintain safety during use.
Q: How is Auramine O prepared for microscopic staining?
A: To prepare a staining solution, dissolve the powder in distilled water or ethanol until the desired concentration (0.1-1% w/v) is achieved. Make sure the working solution is neutral (pH 7.0) for optimal staining performance.
Q: What are the main benefits of using Auramine O for microscopy?
A: Auramine O offers high-purity, effective fluorescent staining and excellent solubility, ensuring vibrant visualization under the microscope. Its stability and compatibility with standard laboratory protocols make it a reliable choice for detailed microscopic analysis.
