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 Brilliant Violet 480
Brilliant™ Violet 480 (BV480) is a green-emitting non-tandem polymer fluorophore that can be excited by the 405 nm Violet laser and collected using a 525/40 bandpass filter. BV480 has an excitation peak at 436 nm and an emission peak at 478 nm, and provides an optimized alternative to BV510. Other dyes that are similar include StarBright Violet 475 (Bio-Rad) While BV480 can be detected on the same filter as BV510, its emmision profile reduces spillover into the BV605, BV650, and BV711 channels. Additionally BV480's excitation profile will reduce cross-laser excitation with the UV laser, resulting in less spillover into UV channels than BV510. These advantages make BV480 an optimal choice for flow cytometry panels using multiple reagents on Violet and/or UV lasers. This dye is part of the Brilliant™ Violet dye line. BV510 and BV480 are the only dyes in the Brilliant™ Violet dye family that are not tandem fluorophores based off the BV421 polymer core, but they have nearly the same maximum excitation.
