MTS-CR110 (MTS-5-(and-6)-carboxyrhodamine 110, mixed isomers) is a green fluorescent thiol-reactive dye. CR110 (5-(and-6)-carboxyrhodamine 110) has absorption and emission spectra (502/524 nm) similar to those of fluorescein (495/519 nm) but its photostability is far better than that of the latter. Thus, MTS-CR110 is a superior green fluorescent dye for labeling thiols. &lamba;Ex/&lamba;Em (MeOH) = 502/524 nm Orange solid soluble in DMF or DMSO Store at -20°C and protect from light C24H21N3O6S2 MW: 511 content/uploads/2018/05/91035.bmp"/>
