Nitric oxide (NO), is arguably one of the most important small signaling
molecules in biological systems. It regulates various biological responses in
both physiological and pathological conditions, often time producing seemingly
contradictory results. The details of the effects of NO are highly dependent on
the level of NO that cells experience and the temporal aspect of when and how
long cells are exposed to NO. Herein, we present a novel measurement system
(CellNO trap) that allows real-time NO measurement via chemiluminescence
detection from general adhesive cultured cells using standard cell culture media
and reagents that does not perturb the cells under investigation. Highly
controlled light-initiated NO releasing polymer SNAP-PDMS was used to
characterize and validate the quantitative data nature of the device. The NO
generation profile from the macrophage cell-line RAW264.7 stimulated by 100ng/ml
LPS and 10ng/ml IFN-? was recorded. Measured maximum NO flux from RAW264.7 varied
between around 2.5-9pmol/10(6)cell/s under 100ng/ml LPS and 10ng/ml IFN-?
stimulation, and 24h cumulative NO varied between 157 and 406 nmol/10(6)cell
depending on different culture conditions, indicating the conventional report of
an average flux or maximum flux is not sufficient to represent the dynamic
characters of NO. LPS and IFN-?'s synergistic effect to RAW264.7 NO generation
was also directly observed with the CellNO trap. The real-time effect on the NO
generation from RAW264.7 following the addition of arginine, nor-NOHA and L-NAME
to the cultured cells is presented. There is great potential to further our
understanding of the role NO plays in normal and pathological conditions clearly
understanding the dynamic production of NO in response to different stimuli and
conditions; use of CellNO trap makes it possible to quantitatively determine the
precise NO release profile generated from cells in a continuous and real-time
manner with chemiluminescence detection.
