Thiol-Reactive Dyes

3,6-dioxaoctane-1,8-diyl dimethanethiosulfonate is a water soluble MTS cross-linker.

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 (catalog no. 91035) except that the former has a X spacer molecule between the dye and the MTS reactive group.

MTS-ROX (MTS-5(6)-carboxy-X-rhodamine) is a fast-reacting and highly selective thiol-reactive rhodamine dye.

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.

2-((4-Azido-2,3,5,6-tetrafluorobenzoyl)amino)ethyl methanethiosulfonate is a cross-linker containing a thiol-reactive MTS group and a photoaffinity label 4-azido-2,3,5,6-tetrafluorobenzene (ATFB). ATFB is known to be a superior photoaffinity label that undergoes highly efficient C-H bond insertion on UV photolysis.

MTS-AMCA (7-amino-4-methylcoumarin-3-acetic acid methanethiosulfonate) readily labels a thiol with AMCA, a widely used UV-excitable, blue fluorescent dye.

MTS-TAMRA (MTS-5(6)-carboxytetramethylrhodamine, mixed isomers) is a fast-reacting and highly selective thiol-reactive label that permits one to attach the popular fluorescent dye carboxytetramethylrhodamine to a thiol group.

AEAETS (2-Aminoethyl 2-aminoethanethiosulfonate dihydrochloride salt) is a doubly positively charged alkanethiosulfonate.

CR110-C6-maleimide (full name: 5(6)-Carboxyrhodamine 110-C6-maleimide) is a maleimide derivative of the green fluorescent dye carboxyrhodamine 110.

MTSPT (3-trimethylammoniumpropyl methanethiosulfonate, bromide salt) is a positively charged MTS reagent.

MTSBS (4-Sulfonatobutyl methanethiosulfonate sodium salt) is a negatively charged MTS reagent.

MTSPA (3-aminopropyl methanethiosulfonate hydrobromide) is a positively charged MTS reagent.

MTSPS (3-sulfonatopropyl methanethiosulfonate sodium salt) is a negatively charged MTS reagent.

MTSEA (2-Aminoethyl methanethiosulfonate hydrobromide) is a positively charged MTS reagent.

MTSEH (2-Hydroxyethyl methanethiosulfonate) is a neutral MTS reagent.

MTSES (2-Sulfonatoethyl methanethiosulfonate sodium salt) is a negatively charged MTS reagent.
