Interestingly, using an antibody raised against a C‐terminal epitope of CYLD, we detected a ~110 kDa protein corresponding with the anticipated molecular weight of CYLD in all cell DLBCL lines, but exclusively in the ABC DLBCL cell lines also a prominent protein of ~70 kDa was observed (Fig. 1D). The gene discussed is CYLD; the disease is diffuse large B-cell lymphoma.
