Avidin D, Rhodamine (TMRITC) labeled, is made from our ultrapure Avidin D and is optimally labeled using tetramethyl- rhodamine isothiocyanate (TMRITC). This label produces a red color and is recommended for routine immunofluorescence applications. Rhodamine provides a second label to fluorescein and is especially useful in avoiding problems associated with endogenous tissue fluorescence. The lower quantum yield of rhodamine compared to fluorescein is compensated for by a reduction in photobleaching rate.
