MTS-CR110-X (MTS-5-(and-6)-carboxyrhodamine 110-X, mixed isomers) is a green fluorescent thiol-reactive dye. It is similar to MTS-CR110, except that the former has a X spacer molecule between the dye and the MTS reactive group. The linker molecule may enhance fluorescence when the dye is attached to proteins. &lamba;Ex/&lamba;Em (MeOH) = 502/524 nm Orange solid soluble in DMF or DMSO Store at -20°C and protect from light C30H32N4O7S2 MW: 624
