SNO actin/β-actin band density ratios from air- and 690-kPa N₂-exposed neutrophils

Data reflect band densities on Western blots of lysates from cells exposed to air or air + 690 kPa of N₂ for 30 min that had been subjected to the biotin switch procedure. PBS, cells incubated with buffer only during air/N₂ exposure; UV, cells exposed to UV light for 5 min after air/N₂ exposure. Other interventions involved incubation with 5 μm cytochalasin D, 1 mm 1400W, or 10 μm Nox2ds during air/N₂ exposure. All values are mean ± S.E. (n = number of independent trials (shown in parentheses)).

Incubation/intervention	Air	N2
PBS	1.00 ± 0.00 (5)	2.50 ± 0.34 (5)a
UV	1.03 ± 0.11 (3)	1.07 ± 0.17 (3)
Cytochalasin D	1.22 ± 0.04 (3)	1.10 ± 0.05 (3)
Nox2ds	0.99 ± 0.09 (3)	1.08 ± 0.14 (3)
1400W	1.04 ± 0.04 (3)	1.08 ± 0.09 (3)
