Overview
Acridine Yellow, also known as Acridine Yellow G, is a synthetic fluorescent dye belonging to the acridine family. It is widely used in biological research for staining nucleic acids and proteins, as well as in the textile industry for dyeing fabrics. The dye exhibits strong fluorescence under UV light, making it valuable in microscopy and diagnostic applications. Acridine Yellow was first synthesized in the early 20th century and has since become a staple in laboratories and industrial settings. Its cationic properties allow it to bind effectively to negatively charged molecules, enhancing its utility in various staining protocols.
Physical and Chemical Properties
Acridine Yellow appears as a yellow to orange crystalline powder with a molecular weight of 237.30 g/mol. It is soluble in water, ethanol, and acetone, which facilitates its use in aqueous and organic solutions. The dye is stable under moderate temperatures but decomposes upon heating beyond 250°C. One of the key characteristics of Acridine Yellow is its fluorescence, which peaks at around 495 nm when excited at 430 nm. This property makes it particularly useful in fluorescence microscopy and flow cytometry. The dye's cationic nature also allows it to interact with cellular components, such as DNA and RNA, for staining purposes.
Main Applications
Acridine Yellow is primarily used in biological research for staining nucleic acids and proteins in cells and tissues. Its fluorescence properties make it ideal for visualizing cellular structures under a microscope. The dye is also employed in flow cytometry to detect and quantify specific cell populations. In the textile industry, Acridine Yellow serves as a dye for synthetic and natural fibers, providing vibrant yellow hues. Additionally, it finds applications in diagnostic kits and as a tracer in environmental studies. Its versatility and stability under various conditions contribute to its widespread use across multiple fields.
Safety and Storage
Acridine Yellow should be handled with care to avoid inhalation or skin contact, as it may cause irritation. Proper personal protective equipment (PPE), such as gloves and goggles, should be worn when working with the dye. In case of exposure, rinse affected areas thoroughly with water and seek medical attention if necessary. For storage, keep Acridine Yellow in a tightly sealed container in a cool, dry place away from direct sunlight. Prolonged exposure to light or moisture may degrade the dye, reducing its effectiveness. Always refer to the safety data sheet (SDS) for specific handling and disposal guidelines.
B2B Procurement Guide
When procuring Acridine Yellow, B2B buyers should prioritize suppliers who provide detailed product specifications, including purity levels and batch testing results. Requesting a certificate of analysis (CoA) ensures the product meets the required standards for your application. Price may vary based on purity and quantity, with bulk purchases often offering cost savings. Consider lead times and shipping conditions, as the dye may require special handling to prevent degradation. Establishing a relationship with a reliable supplier can ensure consistent quality and timely delivery for ongoing needs.
