Figure 1. A selective lack of Egr-1 expression in Egr1-/- cells. Splenocytes from WT and Egr1-/- mice were treated with PMA and ionomycin (P/I) for 1 or 3 h, and assayed by semi-quantitative (A) and quantitative RT-PCR (B). Egr1 mRNA expression was normalized to that for β2m. Data are representative of three independent experiments.
