About CD25
The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains, together with the common gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor, while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein, soluble IL2RA has been isolated and determined to result from extracellular proteolyisis. Alternately-spliced IL2RA mRNAs have been isolated, but the significance of each is presently unknown. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency. Patients with severe Coronavirus Disease 2019 (COVID-19), the disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have significantly elevated levels of IL2R in their plasma. Similarly, serum IL-2R levels are found to be elevated in patients with different types of carcinomas. Certain IL2RA and IL2RB gene polymorphisms have been associated with lung cancer risk.

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.
