NO is a diatomic free radical that has in biological fluids extremely
short half-life (<1 s). The addition of NO to functional proteins is
as important as phosphorylation in its consequences on cellular
activities. In order to be transported and stocked in biological fluids,
NO binds to peptides and proteins forming S-nitrosothiols (RSNOs). The
variation of their proportion has been recognized in many diseases.
RSNO are sensitive to decomposition by light, heat, and metal ions.
RSNOs can exchange the NO between one other by transnitrosation
reaction. Recently we studied the separation of different RSNOs and
their transnitrosation reaction using capillary electrophoresis with
capacitively coupled contactless conductivity detection. Also, we
developed a decomposition process of RSNO using copper to quantify RSNO
by electrochemical techniques (ultra-micro electrodes). We are currently
down scaling these approaches within microchip devices. This opens the
way for an integrated lab-on-a-chip for S-nitrosothiols quantitation.
