(A) Schematic illustration from the WT1 exons and localization with the primers utilised for semi-quantitative RT-PCR (arrows) are proven. (B) Ex4a(+)WT1 mRNA expression was resolute by RT CR working with 4a-F and Ex6-R primer pair that amplifies only Ex4a(+)WT1 isoform in six distinct WT1-expressing cancer cells (AZ-521, HT-1080, LU99B, K562, Kasumi-1 and HL60) and a person WT1-expressiong typica
