The ETV1 5’ FISH Probe is designed to detect the human ETV1 gene 5’-region located on chromosome band 7p21.2. ETV1 is also known as ER81.

The ETV1 5' 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 ETV1 5' FISH probe hybridizes to chromosome 7 in both metaphase and interphase cells. After hybridizing with normal human peripheral blood lymphocyt
e samples, two distinct fluorescent spots are observed in the interphase nuclei, each spot corresponding to the 7p21.2 region on the chromosome 7. In metaphase cells, a “doublet” or “split signal” may appear on chromosomal region 7p21.2. Each signal within the doublet represents one of the two sister chromatids present in the replicated chromosome 7.
