Special Considerations

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 5 unstained slides minimum (one 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.
