  Chromosome Counting Probes
CCP21 (21q22) FISH Probe   Cat No  CT-CCP021
Chromosome 21 Counting Probe             

The CCP21 probe is designed to detect the copy number of chromosome 21 or to serve as a control to determine the relative copy number of genes located on chromosome 21 and other chromosomes.* The probe is ~510 KB covering locus 21q22.2.

 

The CCP21 probe is labeled with CytoOrangeCytoOrange 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 CCP21 probe hybridizes to chromosome 21 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 fluorescent microscope. In metaphase cells, bright signals can be observed on locus 21q22.2.  It shows no cross hybridization with any other chromosomes.
