About CD69
This gene encodes a member of the calcium dependent lectin superfamily of type II transmembrane receptors. Expression of the encoded protein is induced upon activation of T lymphocytes, and may play a role in proliferation. Furthermore, the protein may act to transmit signals in natural killer cells and platelets. [provided by RefSeq, Aug 2011]

About StarBright Blue 615
StarBright Blue 615 (SBB615) Dye is a bright, 488 nm laser excitable dye with a unique, narrow excitation and emission profile and is suitable for conventional and full spectrum flow cytometry. It is brighter than PE-CF594 and PE-Dazzle594 when excited by the 488 nm and is not excited to the same degree by the 561 nm laser. As it is not a traditional tandem dye, SBB615 does not have issues around tandem breakdown and changes to staining over time. SBB615 provides more choice and flexibility when building multicolor panels incorporating the 488 nm laser.
