CytoTest LSP COL1A1 3' FISH ProbeCT-LSP150
The COL1A1 3’ FISH Probe is designed to detect the human COL1A1 gene 3’-region located on chromosome band 17q21.33. COL1A1 is also known as OI4.
The COL1A1 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 COL1A1 3' FISH probe hybridizes to chromosome 17 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 17q21.33 region on the chromosome 17. In metaphase cells, a “doublet” or “split signal” may appear on chromosomal region 17q21.33. Each signal within the doublet represents one of the two sister chromatids present in the replicated chromosome 17.
