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 (de Bruin, 1995). The extracellular domain of CD30 is homologous to that of TNF receptor superfamily members, whereas there is no homology in teh cytoplasmic domain, suggesting major differences in signaling mechanisms (Falini, 1995). CD30 expression is found on Hodgkin and Reed-Sternberg (H-RS) cells, and on activated B and T lymphocytes (de Bruin, 1995). The antibody from the Ber-H2 hybridoma cell line was included in the Fourth International Workshop on Human Leukocyte Differentiation Antigens and was found to belong to the CD30 cluster (Schwarting, 1989).，官网链接：https://www.sigmaaldrich.cn/product/mm/fcmab192f 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
