Real-time quantitative RT-PCR

CHK2 mRNA expression analysis (median and range) in NHLs. Similar CHK2 mRNA expression levels were observed in nonneoplastic reactive lymphoid tissues and different types of NHLs (Kruskal-Wallis test, P > .05). Results are depicted as the ratio of absolute CHK2 to GUS mRNA transcript numbers (RU). Bars indicate SD.
