Figure 5. Effect of CO on heme transfer from ferric-RH to LDL.

The rate of heme transfer to LDL was traced in reaction mixtures containing either Hb or Mb (3 µM), dansylated LDL (100 µg protein/ml) and H₂O₂ (3 µM) at anaerobic conditions provided by N₂ (solid line) or CO (dot-dash line). The two upper lines – Hb and the two lower lines – Mb. (Ex/Em = 327/400 nm). A representative result of 4 independent experiments is shown.
