About CD40L
The protein encoded by this gene is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in an inability to undergo immunoglobulin class switch and is associated with hyper-IgM syndrome. [provided by RefSeq, Jul 2008]

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.
