Human blood plasma advanced oxidation protein products (AOPP) correlates with fibrinogen levels.

In 1996 a novel oxidative stress biomarker, referred to as advanced oxidation protein products (AOPP) was detected in the plasma of chronic uremic patients. The aim of the present studies was to find out that which plasma fraction(s) is responsible for AOPP reactivity. Thermal treatment of pooled samples of human citrate-plasma or EDTA-plasma at 50 degrees C resulted in a rapid and parallel loss of fibrinogen concentration and AOPP reactivity.
