Native Flavobacterium heparinum Chondroitinase B
Cat No.
NATE-1950
Description
Chondroitinase B cleaves, via an elimination mechanism, polysaccharide chains containing 1-4 linkages between hexosamines and iduronic acid residues in dermatan sulfate (chondroitin B).The reaction yields oligosaccharide products (mainly disaccharides) containing unsaturated uronic acids which can be detected by UV spectroscopy at 232 nm.
