Rhodamine-actin conjugates are tools for investigating cytoskeleton dynamics. This fluorescent conjugates are prepared by labelling lysine residues of actin with activated esters of rhodamine dyes. Rhodamine actins have been widely used in fluorescence microscopical studies.
Due to the superior features of modern fluorescence dyes characterized e.g. by significantly higher photostability, conjugates like Atto-actins are by far more suitable for these applications.
