Levels of IFNR mRNA expression in HUT78 variants. The levels of IFNR mRNA were assessed by slot blot analysis. Total poly A+ RNA was isolated from HUT78R and HUT78S cells treated with (+) or without (−) IFNα and diluted with 6.25 mol/L formaldehyde/10X SSPE at 65°C. The treated RNA (10 μg) was transferred to nylon filters, UV-cross-linked and probed with human IFNR cDNA probe labeled with 32[P], followed by autoradiography.
