LSP EWSR1 3 FISH Probe

The EWSR1 3’ FISH Probe is designed to detect the human EWSR1 gene 3’-region located on chromosome band 22q12.2. EWSR1 is also known as EWS or bK984G1.4.

The EWSR1 3 FISH probe is labeled with CytoGreen. CytoGreen is a fluorophore with an excitation peak at 495nm and emission peak at 518nm, giving it a green fluorescent signal with the appropriate filters.

The EWSR1 3 FISH probe hybridizes to chromosome 22 in both metaphase and interphase cells. After hybridizing with normal human peripheral blood lymphocyte samples, two distinct fluorescent spots are observed in the interphase nuclei, each spot corresponding to the 22q12.2 region on the chromosome 22. In metaphase cells, a “doublet” or “split signal” may appear on chromosomal region 22q12.2. Each signal within the doublet represents one of the two sister chromatids present in the replicated chromosome 22.
