Heparin is labeled with both biotin and fluorescein, Ex/Em wavelength 494/518 nm. Purity: >95% lyophilized powder. Degree of substitution: 1 mol % substitution for each dye and at least one biotin and one fluorescein molecule per polymer.
Heparin is a member of the glycosaminoglycan family of carbohydrates (which includes the closely related molecule heparan sulfate) and consists of a variably sulfated repeating disaccharide unit. The most common disaccharide unit in heparin is composed of a 2-O-sulfated iduronic acid and 6-O-sulfated, N-sulfated glucosamine, IdoA(2S)-GlcNS(6S).
