CD30 Antibody Staining Protocol for Immunohistochemistry

 

Description: This antibody labels anaplastic large-cell lymphoma (ALCL) and Reed-Sternberg cells, and is a useful tool for the identification of ALCL and as a secondary marker for Hodgkin’s disease. CD30 is a transmembrane cytokine receptor belonging to the tumor necrosis factor (TNF) receptor superfamily. Mature CD30 has a molecular mass of 120 kDa and is derived from a 90 kDa precursor protein. The extracellular domain of CD30 is homologous to that of TNF receptor superfamily members, whereas there is no homology in the cytoplasmic domain, suggesting major differences in signalling mechanisms. The intracellular part of CD30 possesses kinase activity, indicating that CD30 plays a role in regulating the function, differentiation and/or proliferation of normal lymphoid cells. A soluble 85 kDa form of CD30, sCD30, released from the membrane-bound molecule by proteolytic cleavage, can be detected in the sera of patients with CD30-expressing neoplasms. CD30 expression is found on Hodgkin and Reed-Sternberg (H-RS) cells, anaplastic large-cell lymphoma cells, and on activated B and T lymphocytes. In non-lymphoid tissues and neoplasms, CD30 expression has been confirmed in embryonal carcinomas, seminomas, decidual cells and mesotheliomas.
