Clinical Applications
- Myeloproliferative Neoplasm (MPN)

Normal Cell:
Two green-orange-blue colocalization/fusion signals
(2BGO).

Aberrant Cell (typical results):
One blue-green-orange colocalization/fusion signal (1BGO) and one blue-green colocalization/fusion (1BG) resulting from loss of one orange signal.
