Figure S6. FISH validation of 9p24.1 copy number loss. A) DNA content histogram of flow-sorted TNBC-8. B) Chromosome 9 Comparative Genomic Hybridization plot with (log2 ratio − 1) loss of JAK2 locus (arrow) at 9p24.1. C) Multi-color FISH assay [5′JAK2[9p24](green)/ 3′JAK2[9p24](red)/CEN 9(aqua)] image indicates 0–2 intact JAK2 signals and 1–4 CEN 9 signals.
