Thiol-Reactive Dyes

MTSET (2-(Trimethylammonium)ethyl methanethiosulfonate, bromide) is a positively 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.

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

N-(1,10-Phenanthrolin-5-yl)iodoacetamide has been used to label thiols to confer the metal-binding properties of the phenanthroline chelator. For example, completing of the chelator with copper can be used to selectively cleave RNA or DNA in the presence of hydrogen peroxide.

N-(6-Aminohexyl)maleimide is a cross-linking reagent that can react with an amine-reactive group and a thiol group.

NFQ1, a non-fluorescent quencher, is used for a new type of One Sample Fluorescence Resonance Energy Transfer (OS-FRET) method employing a novel, non-fluorescent methanethiosulfonate-linked acceptor that can be reversibly coupled to a target sulfhydryl residue via a disulfide bond.

5(6)-ROX maleimide has C6-linker that enhances the fluorescence after the dye is conjugated to proteins. The product is a direct replacement of 5(6)-carboxy-X-rhodamine C5-maleimide (91041).

TCEP hydrochloride is an odorless reducing agent that is more stable and effective than dithiothreitol (DTT) or 2-Mercaptoethanol. TCEP hydrochloride is soluble in water to 310 grams per liter.

5(6)-Carboxytetramethylrhodamine maleimide has C6-linker that enhances the fluorescence after the dye is conjugated to proteins. The product is a direct replacement for 5(6)-carboxytetramethylrhodamine C5-maleimide (91040).
