Abstract:The chondroitin 4- and 6-sulfate proteoglycan monomers from two differentiating tissues (brain and muscle of 14-day chick embryos) were compared by indirect means, including use of chondroitinase AC, with the major class of cartilage chondroitin sulfate proteoglycan monomers. In addition to slower sedimentation in sucrose density gradients, the monomers from both noncartilaginous tissues have longer chondroitin sulfate chains and exhibit little difference in the susceptibilities of their core proteins to papai… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
