The TBX1 probe is 211kb, labeled in red, covers the entire TBX1 gene and includes the D22S1627 marker. The N85A3 (44kb), labeled in green, is located within 22q13.3 and covers the telomeric end of the SHANK3 gene, allowing for identification of the most distal 22q13.3 deletions. The two unique sequences act as control probes for each other and allow identification of chromosome 22.
Not only do CytoCell offer an extensive range of high-quality FISH probes, the customer support is also excellent — providing fast access to all the probes I need. The probes are highly consistent with bright signals allowing easy scoring of results.
