Fluorescence in situ hybridization has become an essential detection assay in today´s routine diagnostics. However, long hybridization times of many hours to overnight are still a restrictive factor. We have refined the production process of our FISH probes to reduce background and artefacts and to improve the signal to noise ratio, particularly in short-time hybridization. Since mid-2015, one hour hybridization on lymphocytes is an integral part of quality control for all XCyting locus-specific probes at our manufacturing facility.

Myxoid liposarcomas (MLS) are accounting for about 30% of liposarcomas and represent approximately 10% of adult soft tissue sarcomas. Patients with MLS showing progression to round-cell morphology have an inferior outcome. The most common aberration in MLS is the translocation t(12;16)(q13;p11) with a frequency of about 95% and to a much lesser extend t(12;22)(q13;q12), in which FUS is not involved. These reciprocal translocations are resulting in the generation of FUS-DDIT3 and EWSR1-DDIT3 fusion genes, respectively. As FUS is also involved in the development of low-grade fibromyxoid sarcoma with the rearrangement t(7;16)(q33;p11), FUS rearrangements are not highly specific for the detection of MLS. Human models of sarcomagenesis suggest that the FUS-DDIT3 fusion gene impedes with adipogenic differentiation of mesenchymal stem cells and thereby contributes to the development of liposarcoma.
- Solid Tumors (Solid Tumors)
Two green-orange colocalization/fusion signals (2GO).
Aberrant Cell (typical results):
One green-orange colocalization/fusion signal (1GO), one separate green (1G) and orange (1O) signal each resulting from a chromosome break in the respective locus.
