The CCPY (DYZ1) probe is designed to detect the copy number of chromosome Y or to serve as a control to determine the relative copy number of genes located on chromosome Y and other chromosomes.* The probe is derived from chromosome Y long arm specific alpha satellite DNA (DYZ1). 

The CCPY (DYZ1) probe is labeled with CytoGreen or CytoOrange. CytoGreen is a fluorophore with an excitation peak at 495 nm and emission peak at 518 nm, giving it a green fluorescent signal with the appropriate filters; CytoOrange is a fluorophore with an excitation peak at 551 nm and emission peak at 575 nm, giving it an orange fluorescent signal with the appropriate filters. The probe can also be labeled in different colors; please contact us with your specifications.

The CCPY (DYZ1) probe hybridizes to chromosome Y in both metaphase and interphase cells. After hybridizing with normal human peripheral blood lymphocyte samples, two distinct bright fluorescent spots could be observed in the interphase nuclei under a fluorescence microscope. In metaphase cells, bright signals can be observed on the centromere region of chromosome Y (Yp11.1-q11.1). No cross-hybridization to loci on other chromsomes is observed.
