Type I IFN dose-response analysis of J2E cell growth.
J2E cells were seeded at 5 × 104 cells/mL and stimulated with IFN-α1, -α2, -α4, -α5, -α6, -α9, or -β (1-1000 IU/mL) as indicated. Cell number was determined by eosin exclusion at 48 hours of culture (statistical significance compared with unstimulated J2E cells, *P ≤ .05; **P ≤ .01; mean ± SE, n = 3).
