Probe specification

  • SYT, 18q11.2, Red

Probe information

Synovial sarcomas account for up to 10% of soft-tissue sarcomas, typically arising in the para-articular regions in adolescent and young adults1.

A characteristic SYT(SS18)-SSX fusion gene resulting from the chromosomal translocation t(X;18)(p11;q11.2) is detectable in more than 90% of synovial sarcomas2, suggesting this is the primary causal event. The translocation fuses the SYT gene from chromosome 18q11.2 to either of two highly homologous genes at Xp11: SSX1 (Synovial Sarcoma X Breakpoint 1) or SSX2. In less than 1% of cases, SYT will be fused to a third gene, SSX43. SYT-SSX1 and SYT-SSX2 are thought to disrupt transcription and the subsequent expression of specific target genes4,5.

FFPE tissue preparation and FISH protocol

Select a protocol step to view:

Heat pretreatment

1. Heat Pretreatment Dark Blue
  • Heat 50ml Tissue Pretreatment Solution (Reagent 1) in a porcelain wash jar or coplin jar immersed in a waterbath until it is either boiling or 98 - 100°C.
  • Boil slides for 30 minutes (Note: different incubation times may be required depending on tissue fixation. A 30-minute incubation is a recommended starting point).
  • Wash in PBS or dH2O at room temperature (RT) for 2 x 3 minutes.
