The D13S319/TP53 FISH Probe Kit is designed to detect the human D13S319 marker region located on chromosome band 13q14.2 and the human TP53 gene located on chromosome band 17p13.1. Abnormalities in the two regions are commonly found in hematological and solid tumor types.

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.
