About CD8a
The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell-cell interactions within the immune system. The CD8 antigen acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class I MHC molecules. The coreceptor functions as either a homodimer composed of two alpha chains or as a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains. This gene encodes the CD8 alpha chain. Multiple transcript variants encoding different isoforms have been found for this gene. The major protein isoforms of this gene differ by the presence or absence of a transmembrane domain and thus differ in being a membrane-anchored or secreted protein. [provided by RefSeq, May 2020]

About Spark Red 718
Spark Red™ 718 is a brighter alternative to Alexa Fluor® 700, adding to the fluorophore options for the red laser that can detect antigens with lower expression levels. It can be used on a conventional cytometer with a 633 nm red laser and 720/45 filter set (or equivalent filter used to detect Alexa Fluor® 700) spectral cytometers with appropriate instrument settings. On conventional cytometers, Spark Red™ 718 can be utilized with both APC and APC/Cyanine7. On spectral cytometers, it can be unmixed from APC, Spark NIR™ 685, Alexa Fluor® 660, APC/Cyanine7, and APC/Fire™ 810. As spectral properties of Spark Red™ 718 and Alexa Fluor® 700 are nearly identical, using them together in a multicolor panel is not recommended. With a medium brightness, Spark Red™ 718 is best suited for detecting antigens with low to moderate expression levels.
