Schematic representation of EVI1 andMDS1-EVI1 and the primer and probes used for real-time PCR.

Primers 1 and 2 plus probe A were used to determineMDS1-EVI1 expression levels. EVI1transcript levels were determined using primers 3 and 2 plus probe A.MDS1 expression was measured using primers 1 and 4 plus probe B. Probe C was used for Northern blot analysis.
