An “Eprobe leukemia panel kit” based on this Eprobe mediated RT-qPCR assay, equipped with synthetic quantitative standard RNAs with strict quality control and additional targets including CBFb-MYH11, ETV6-AML1, MLL-AF4, and MLL-AF9 rearrangements is currently under development. This evidence concerns the gene AFF1 and leukemia.
