- Peripheral blood: 5-10 mL in EDTA tube (purple top) preferred; ACD (yellow top) acceptable
- Fresh Tissue: Minimum of 250 mg tissue in RPMI transport media
- Formalin-Fixed Paraffin-Embedded Tissue: 1 H&E slide cut to 4 microns and 6-8 slides cut at 8 microns of BM clot or tissue fixed with 10% NBF fixative on non-charged slides. Please circle tumor for microdissection. Alternatively, the FFPE clock of the BM clot can be sent for sectioning in our lab.
