LY CH Dilithium Salt is a polar, cell-membrane impermeant, green-fluorescent dye that is reactive with aldehydes and ketones on biomolecules. The carbohydrazide group is reactive with aldehydes and ketones and may be used to label or detect polysaccharides and glycoproteins. This dye may also be reacted with carboxylic acids of peptides, proteins, and other biomolecules using a carbodiimide like water-soluble EDAC. Lucifer yellow carbohydrazide Li salt is commonly used as a fluorescent stain for investigations of neuronal morphology because the carbohydrazide group is readily bonded to surrounding biomolecules during aldehyde-based tissue fixation. The lithium salt form is commonly used due to its enhanced water solubility, but we also offer the potassium salt form (Product 6605). These membrane-impermeant dyes are commonly loaded into live cells by microinjection, pinocytosis, scrape loading, or ATP-induced permeabilization. LY CH Dilithium Salt is excited near 428 nm and has a fluorescent emission near 535 nm. .
