Lipocalin-2 protein levels in protein extracted from the liver of female fetuses at d21 of gestation. a The pixel density of replicate 100 μg samples ± SEM (n = 6). Data were analyzed by one-way ANOVA P = 0.017, and columns sharing a superscript letter are not significantly different (P > 0.05). A typical blot is shown in the lower panel Sal = 25 μg protein extracted from the liver of an adult rat infected with Salmonella enterica (Robertson et al. 2003). b Correlation between Lcn2 protein expression (pixel density on Western blots) and mRNA (relative expression by RT-PCR) of a subset of samples, n = 6 per treatment. Line fitted by linear regression (P < 0.001, R 2 = 0.32)
