About CD244
This gene encodes a cell surface receptor expressed on natural killer (NK) cells (and some T cells) that mediate non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via this receptor is thought to modulate NK-cell cytolytic activity. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

About PerCP-Cy5.5
PerCP-Cyanine® 5.5 (PerCP-Cy5.5) is a red-emitting tandem fluorophore that was originally designed to make the PerCP fluorophore more stable and increase signal intensity. The donor molecule, PerCP can be excited by the 488-nm blue laser and and transfers energy to the acceptor molecule, Cy5.5, which emitts light that can be captured with a 695/40 nm bandpass filter. PerCP-Cy5.5 has an excitation peak at 482 nm and an emission peak at 695 nm. There are superior alternatives to PerCP and PerCP-Cy5.5 including BB700, NovaFluor Blue 690 or PerCP-eFluor™ 710
