LSP ETV1 5 FISH ProbeCT-LSP099
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 lymphocyte 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.
