useful for research of chondroitin sulfate
Chondroitin sulfate (CS) is a sulfated glycosaminoglycan composed of repeating disaccharide units of N-acetyl-D-galactosamine (GalNAc) and D-glucuronic acid (GlcUA). CS is abundant in cartilage and exists as unbranched polysaccharidechains covalently linked to the protein core of proteoglycans. These products are prepared by the fluorescent labeling of CS derived from whale cartilage (FACS-A1), shark cartilage (FACS-C1 and D1), squid cartilage (FACS-E1) according to the method of Ogamo et.al.1). Fluoresceinamine molecules are chemically attached to carboxyl groups of the glucuronic acid of CS. These solutions are dissolved in PBS (-) and sterilized by filtration. The endotoxin content is in accordance with the product specifications. The excitation wavelength is 490~500 nm and the emission wavelength is 515~525 nm. The enclosed Certification of Analysis lists actual values for product specifications.
