CD40 Monoclonal / PE-Vio770 / HB14

Product Details
Description The HB14 monoclonal antibody reacts with human CD40, a 45–50 kDa type I transmembrane glycoprotein and member of the tumor necrosis factor receptor (TNFR) superfamily. It is expressed primarily on B cells, macrophages, dendritic cells, endothelial cells, and fibroblasts and at lower levels on plasma cells and a subset of peripheral T cells. CD40 is involved in B cell differentiation and proliferation, isotype class-switching, and protection of B cells from apoptosis. Interaction of CD40 with its ligand CD154 is important in T cell–B cell interaction and plays a role in co-stimulation and immune regulation. Clone HB14 blocks the binding of CD40 to CD154.

About CD40
This gene is a member of the TNF-receptor superfamily. The encoded protein is a receptor on antigen-presenting cells of the immune system and is essential for mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. AT-hook transcription factor AKNA is reported to coordinately regulate the expression of this receptor and its ligand, which may be important for homotypic cell interactions. Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction. The interaction of this receptor and its ligand is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis. Mutations affecting this gene are the cause of autosomal recessive hyper-IgM immunodeficiency type 3 (HIGM3). Multiple alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Nov 2014]
About PE-Vio770
PE-Vio® 770 from Miltenyi Biotec is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Vio®770. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Vio®770, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-Vio®770 has an excitation peak at 565 nm and an emission peak at 775 nm and is a common alternative to PE-Cy7 and PE-H7.
