IRF4 6p25 Rearrangement, paraffin
Use
FISH testing on paraffin-embedded cells for detection of IRF4 (6p25) gene rearrangement. IRF4 rearrangements are most frequently observed in lymphoid neoplasms, including diffuse large B-cell lymphoma, classic Hodgkin lymphoma, follicular center cell lymphoma, and marginal zone B-cell lymphoma.
Special Instructions
Tissues should be fixed in 10% neutral buffered formalin (NBF). Tissues preserved in B+ fixative or decalcified are usually not suitable for FISH. Assay requires 3 unstained slides minimum (two for each probe) and one H&E stained slide. If unstained slides are sent, cut FFPE tissue sections at 3-5 μm thickness, mounted on positively charged slides.
Limitations
Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs specified in the biopharma study contract.
