CytoTest LSP ERG 5' FISH ProbeCT-LSP093
The ERG 5’ FISH Probe is designed to detect the human ERG gene 5’-region located on chromosome band 21q22.2. ERG is also known as p55 or erg-3.
The ERG 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 ERG 5' FISH probe hybridizes to chromosome 21 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 21q22.2 region on the chromosome 21. In metaphase cells, a “doublet” or “split signal” may appear on chromosomal region 21q22.2. Each signal within the doublet represents one of the two sister chromatids present in the replicated chromosome 21.
