The ARHGAP39/CCP8 FISH Probe Kit is designed to detect the human ARHGAP39 gene located on chromosome band 8q24.3, along with the number of chromosome 8 copies per cell. Mutations in ARHGAP39 – also known as CrGAP or Vilse – are associated with a variety of cancers including breast, hepatocellular, prostate and 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 an green fluorescent signal with an appropriate filter.
