The 90220 monoclonal antibody specifically binds to the beta subunit (IL-10R beta/IL-10RB/IL-10Rβ) of the heteromeric IL-10 Receptor complex. This type I transmembrane glycoprotein is also known as, subunit 2 (IL-10R2) or CD210b. The IL-10 Receptor complex is formed by the binding of dimeric IL-10 to two cell surface alpha subunits of the IL-10 Receptor (CD210a/IL-10RA/IL-10Rα). This complex can then recruit two CD210b subunits resulting in the transduction of intracellular JAK/STAT pathway signals. CD210b is also a component of cytokine receptor complexes specific for IL-22, IL-26, IL-28 and IL-29. CD210b is expressed by a variety of cell types including T cells, B cells, NK cells, monocytes and macrophages.
The antibody was conjugated to BD Horizon BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. With an Ex Max near 348 nm and an Em Max near 395 nm, BD Horizon BUV395 can be excited by the ultraviolet laser (355 nm) laser and detected with a 379/28 filter. This dye has been exclusively developed by BD Biosciences as an optimal dye for use on instruments equipped with the ultraviolet laser and has virtually no spillover into any other detector.
