Recombinant Human CD40, Fc-tagged

Cat.No.: CD40-144H
Product Overview: The Fc portion of human IgG1 is fused to the C-terminus of human CD40 (aa 21-193).
Description: CD40 belongs to the TNF-receptor superfamily and is essential in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development and germinal center formation. The interaction of CD40-CD40L is necessary for amyloid-β-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. CD40 is constitutively expressed by antigen presenting cells, including dendritic cells, B cells and macrophages. Consistent with its widespread expression on normal cells, CD40 is also expressed on a wide range of tumor cells, including non-Hodgkins and Hodgkins lymphomas, myeloma and some carcinomas including nasopharynx, bladder, cervix, kidney and ovary.
