The ACP1/CCP2 FISH Probe Kit is designed to detect the human ACP1 gene located on chromosome band 2p25.3, along with the number of chromosome 2 copies per cell. Abnormalities in ACP1 – also known as HAAP, LMWPTP or LMW-PTP – occur in a variety of cancers including gastrointestinal, prostate, breast, chronic myeloid leukemia (CML) and others.

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.
