CAS 6409-77-4

Nuclear Fast Red

Description:

Nuclear Fast Red, with the CAS number 6409-77-4, is a synthetic dye primarily used in histology and cytology for staining biological tissues. It is known for its ability to bind to nucleic acids, making it particularly useful for highlighting cell nuclei in microscopic preparations. This dye exhibits a vibrant red color, which enhances the contrast of cellular structures against the background of tissue sections. Nuclear Fast Red is often employed in conjunction with other stains, such as hematoxylin, to provide a clearer visualization of cellular components. The dye is soluble in water and is typically used in aqueous solutions for staining procedures. Its application extends beyond histology to include various biological and medical research fields, where it aids in the identification and analysis of cellular morphology. Safety data indicates that, like many chemical dyes, it should be handled with care, using appropriate personal protective equipment to avoid skin and eye contact.

Nuclear fast red

CAS: 6409-77-4

Nuclear fast red (NFR) is a fluorescent dye that binds to the DNA of cells in tissue sections. NFR has been shown to bind to the nuclear region of cells, where it can be used as a marker for disease activity or cell nuclei. It is commonly used in immunofluorescence staining and flow cytometry. Disulfide bonds are present in this molecule and are important for its stability and function. When disulfide bonds are broken, the dye becomes non-fluorescent. Nuclear fast red is a monosodium salt with a molecular weight of 694.3 g/mol and an empirical formula of C 34 H 29 NO 10 Na 2 .
