SDS-PAGE analysis of differentially salt (NaCl)-precipitated collagens from hoki cartilage. Lanes 2–5, from pepsin-soluble fraction. Lanes 6–9, from alkaline-soluble fraction. Lanes 1 and 10, Broad range marker; lanes 2 and 6, proteins precipitated by 0.8 M NaCl; lane 3, proteins precipitated by 1.0 M NaCl; lane 7, proteins precipitated by 1.2 M NaCl; lanes 4 and 8, proteins precipitated by 2 M; lanes 5 and 9, same proteins as in lanes 4 and 8 after incubation with a reducing agent.
