To ensure precision in the automated staining protocol, we stained identical samples of tonsil, Burkitt lymphoma, and 22 DLBCL cases including the primary DLBCL case #9 (DLBCL with MYC-translocation near the cut-point for MYC IHC-High) three times. The gene discussed is MYC; the disease is diffuse large B-cell lymphoma.
