In vivo hypoxia inducesp5n-Igene expression in day-11 RBCs. Chicken embryos that had been incubated under normoxic conditions for 11 days were exposed to 13.2% O2 for 106 to 127 minutes. The RBC RNA (10 μg per lane) of 5 normoxic and 5 hypoxic embryos was analyzed for p5n-I expression by Northern blot analysis.
