Expression of other C/EBP family members in C/EBPɛ-deficient neutrophils. RNA harvested from peritoneal lavage cells (4 hours after thioglycollate challenge) was resolved by electrophoresis, transferred to Nytran, and hybridized with C/EBP-specific ³²P-–dCTP-labeled probes. C/EBPɛ-deficient neutrophil RNA (−/−); wild-type (+/+).
