IL-1β expression in response to hyperoxia. A. Specific primers used to detect IL-1β gene and β-actin gene expression. B. Samples of RT-PCR amplicons corresponding to the IL-1β gene (578 bp) showing increased expression of IL-1β gene at day 14. C. Samples of RT-PCR amplicons corresponding to the β-actin gene. Lane L: 100 bp ladder, lane N: negative control, lanes 1–5: β-actin amplicons from samples at different dates.
