CD34, technical only
Use
CD34 antigen is selectively expressed on lymphoid and myeloid hematopoietic progenitor cells (blasts) and vascular endothelial cells. CD34 IHC is a helpful tool for differentiating between soft tissue neoplasms. Technical component only. Pathologist read not included.
Special Instructions
Fresh Tissues should be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer term storage if needed. Samples must be tested 3 months after placing in ethanol. Unstained slides require positively charged glass slides to prevent background staining and tissue loss, and should be left unbaked.
Limitations
The test is technical only, meaning it does not include a pathologist's read. Specimens must be fixed in 10% neutral buffered formalin or B plus. All other fixatives will be rejected.
