useful for research of chondroitin sulfateHeparan sulfate (HS) is a sulfated glycosaminoglycan composed of repeating disaccharide units of D-iduronic acid (IdoUA) or D-glucuronic acid (GlcUA) and N-acetyl-D-glucosamine or N-sulfo-glucosamine. HS is abundant in basement membrane of kidney and blood vessel exists as unbranched polysaccharide chains. This product is prepared by the fluorescent labeling of HS derived from porcine kidney according to the method of Ogamo et al.1). Fluoresceinamine molecules are chemically attached to carboxyl groups of the GlcUA or IdoUA of HS. This solution is dissolved in PBS (-) and sterilized by filtration. 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.
