  Chromosome Counting Probes
CCP20 FISH Probe   Cat No  CT-CCP020
Chromosome 20 Counting Probe             

The CCP20 probe is designed to detect the copy number of chromosome 20 or to serve as a control to determine the relative copy number of genes located on chromosome 20 and other chromosomes.* The probe is derived from chromosome 20 specific alpha satellite DNA. 

 

The CCP20 probe is labeled with CytoGreen. 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. The probe can also be labeled in different colors; please contact us with your specifications.

The CCP20 probe hybridizes to chromosome 20 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 20 (20p11.1-q11.1). No cross-hybridization to loci on other chromsomes is observed.
