CLF is a fluorescein-labeled bile acid analog that closely parallels the cellular binding and uptake properties of cholic acid derivatives. It is a divalent 'unipolar' anionic fluorescent monohydroxy bile salt analog with physical, biological and cholestatic properties that are similar to those of lithocholate, glycolithocholate and their derivatives and thus offers a potentially useful probe for studying mechanisms of monohydroxy bile salt-induced cholestasis at the hepatocellular level. CLF is currently used as a tool for the visualization of bile acid transport within liver tissue.
