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 NovaFluor Yellow 700
The NovaFluor family of fluorescent polymers from Thermo Fisher Scientific are a novel reagent for traditional and spectral flow cytometry. These fluorophores are comprised of a DNA backbone polymer integrated with fluorophore substituted nucleosides to create a potent donor molecule. Tandem fluophores with long Stokes' Shift enable brighter, spectrally discrete, tunable fluorescent polymers as an alternative to traditional simple organic structures, protein-based fluorophores as well as the Horizon Brilliant™ family of fluorescent polymers from BD. NovaFluor Yellow 700 is designed to be discreetly excited by the 561nm laser and has an excitation peak at 552 nm and an emission peak at 700 nm.
