Figure 3 showed four examples, cell line KASUMI-1 with AML1-ETO, K-562 with BCR-ABL b3a2 splice variant, AML patient with PML-RARA S-form, and ALL patient with E2A-PBX1(I), respectively. As could be seen, the signal from the GUS-gene was present in all samples (row L). Here, RARA is linked to acute myeloid leukemia.
