特異性:Recognizes 2-3 disaccharide units on both skeletal (type II) and corneal (type I) keratan sulfate chains either in isolated or proteoglycan-bound form. The epitope is resistant to proteolytic or alkaline cleavages and is partially sensitive to keratanase or other endo-b-galactosidase treatment. Species Crossreactivity: human, bovine, sheep, porcine, canine and mouse (adult). No crossreactivity with chicken limb bud proteoglycans, dermatan sulfate proteoglycans of cartilage and proteoglycans of rat chondrosarcomas
