The TP73/ABL2 FISH Probe FISH Probe Kit is designed to simultaneously detect rearrangements involving the human TP73 and ABL2 genes, located on chromosome bands 1p36.32 and 1q25.2, respectively. Deletions and other abnormalities of these regions have been observed in gliomas, astrocytomas and various other malignancies.

The probe is labeled with CytoOrange and CytoGreen. CytoOrange is a fluorophore with an excitation peak at 551 nm and emission peak at 575 nm, giving it an orange fluorescent signal with an appropriate filter; CytoGreen has an excitation peak at 495 nm and emission peak at 518 nm, giving it a green fluorescent signal with an appropriate filter.
