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 PerCP-eFluor 710
PerCP-eFluor™ 710 (PerCP-eF710) is a red-emitting tandem fluorophore that combines PerCP and eF710. The donor molecule, PerCP can be excited by the 488-nm blue laser and and transfers energy to the acceptor molecule, eF710, which emitts light that can be captured with a 695/40 nm bandpass filter. PerCP-eF710 has an excitation peak at 482 nm and an emission peak at 710 nm, and is considered a slightly-red shifted but brighter alternative to PerCP-Cy5.5. This dye and associated products are mostly used for flow cytometry. This dye is part of the larger eFluor™ dye family, developed by eBioscience which is now part of ThermoFisher Scientific.
