[Chemiluminescence of human blood serum fractions activated by bivalent iron ions]

Chemiluminescence of separate human serum fractions induced by ferrous iron ions was studied. After removal of apoB-containing lipoproteins from serum by ultracentrifugation the bottom fraction demonstrated a more intense chemiluminescence and the whole serum luminescence could not be expressed as a simple sum of its individual components. Among various ultra-weak luminescence parameters the intensity of the slow flash measured at the 15th minute after Fe2+ introduction correlated with the level of malonic dialdehyde in apoB-containing lipoproteins.
