Proteoglycans were separated by high-performance liquid chromatography (HPLC), using 2 coupled Aquapore columns containing glycerylpropylsilane groups covalently linked to large-pore (50-100 nm) silica spheres. This 2-column HPLC system was effective in separating cartilage proteoglycan aggregates and monomers [from rat chondrosarcoma, calf and dog], without altering their biochemical integrity. This system was also effective in resolving small amounts of isotopically labeled proteoglycans synthesized by cultured mammalian [human fibroblast, primate smooth muscle] cells. The small sample size, short analysis time, and high reproducibility represent improvements in the study of proteoglycans over conventional soft-gel chromatography.
