Isolation and chemical characterization of two distinct "link proteins" from bovine nasal cartilage proteoglycan complex.
Bovine nasal cartilage proteoglycan aggregates have been dissociated and separated by dissociative density gradient centrifugation into proteoglycan sub-units and "link fraction". The latter contained mainly the two "link proteins" as shown by analytical sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The two "link proteins" were then separated by preparative gel electrophoresis under dissociative conditions. Molecular weight and amino acid composition of both proteins are presented.
