About CD89
This gene is a member of the immunoglobulin gene superfamily and encodes a receptor for the Fc region of IgA. The receptor is a transmembrane glycoprotein present on the surface of myeloid lineage cells such as neutrophils, monocytes, macrophages, and eosinophils, where it mediates immunologic responses to pathogens. It interacts with IgA-opsonized targets and triggers several immunologic defense processes, including phagocytosis, antibody-dependent cell-mediated cytotoxicity, and stimulation of the release of inflammatory mediators. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

About Brilliant Violet 650
Brilliant™ Violet 650 (BV650) is a red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 660/20 bandpass filter. BV650 has an excitation peak at 405 nm and an emission peak at 645 nm. Due to its unique Stokes shift, not many dyes have identical excitation and emission spectrums, but the nearest alternatives include SuperBright 645, Qdot® 655 and eFluor™ 650NC (ThermoFisher). BV650 exhibits a medium level of brightness and is most often used in flow cytometry, specifically, it is an alternative to nanocrystals used for intracellular flow. This dye is part of the Brilliant™ Violet dye line of fluorescent polymers. Brilliant™ Violet 421 polymer is employed as the donor molecule in a series of tandem dyes with acceptor molecules emitting at various points across the visible light spectrum. The Brilliant™ Violet dyes are a superior alternative to QDot nanocrystals and similar to SuperNova dye from Beckman Coulter and StarBright dyes from Bio-Rad.
