Negative control was performed by omitting the primary antibody. Sections were viewed with filter cubes appropriate for DiI (rhodamine filter), Alexa 488 and 355.

...Western immunoblots of transfected or untransfected HEK cells were performed as recently reported (19). In brief, these were lysed using a buffer containing 100 mM Tris HCl (pH 6.8), 200 mM dithiothreitol, 4 % SDS, 20 % glycerol and a cocktail of protease inhibitors (Sigma), and separated on 10 % polyacrylamide gel. After blocking with Tris saline buffer (TBS) containing milk, Tween 20 and preimmune serum, proteins were incubated overnight at 4°C with an anti-P2X3 antibody (Neuromics; 1:2000). Immunocomplexes were incubated for 1 h with a peroxidase-conjugated secondary antibody (Sigma; 1:4000) and detected with a chemiluminescence ECL kit (Amersham). Negative controls were obtained by mock transfection of HEK cells with the pEGFP-N1 plasmid (CLONTECH). Controls for efficient loading of different lysate materials were carried out by using an anti-β actin antibody (mouse monoclonal, 1:2000, Sigma)...

Five eyes (5 animals) from either hyperoxia- or non-hyperoxia-treated mice were enucleated and fixed for 48 hr at 4°C in paraformaldehyde (Sigma-Aldrich, St Louis, MO, USA). Afterward, eyes were immersed for cryoprotection in graded sucrose solution (5% overnight, 10%, 15%, and 20%) and interlocked with resin. Fourteen micron sections were obtained (Shandon AS325 Retraction Microtome, Thermo Scientific, Waltman, MA, USA) and fixed on polylysine-treated glass slides. After overnight incubation in primary antibody (P2X1 1:1000,  P2X2 1:1000,P2X3  1:1000, and  P2Y2 1:800) (Neuromics, Minneapolis, MN, USA) at 4°C, sections were treated with biotinylated secondary antibodies followed by an avidin peroxidase complex step (Vectastin Elite ABC, Vector Laboratories, Burlingame, CA, USA). Finally, a color reaction was obtained using 3,3'-diaminobenzidine (DAB)/nickel-enhanced solution for staining (Sigma-Aldrich, St Louis, MO, USA). At least 6 sections per retina were analyzed. For immunofluorescence, the sections were labeled with lissamine rhodamine-conjugated goat anti-rabbit Ig-G or with fluorescein-5-isothiocyanate-conjugated goat anti-guinea pig Ig-G (Jackson Immunoresearch Laboratories, West Grove, PA, USA). At least 6 sections per retina were analyzed. Visualization was done using a Nikon Fluorescence Eclipse Microscope (Tokyo, Japan), and photographs were taken with a Nikon DN 100 Digital Camera (Tokyo, Japan).

For immunostaining, 2-3μm thick serial sections were cut, deparaffinized and subjected to a heat-induced epitope retrieval step before incubation with antibodies. Sections were immersed in sodium citrate buffer solutions at pH 6.0 and heated in a high-pressure cooker. The slides were rinsed in cool running water, washed in Tris-buffered saline (pH 7.4), and incubated with primary antibodies. The primary antibodies included rabbit polyclonal antibodies against P2X1 (Neuromics, Edina, Minnesota, USA, dilution 1:5000).
