About CD158b
Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.

About Brilliant Violet 786
Brilliant™ Violet 786 (BV786) is a far-red-emitting tandem fluorophore that can be excited by the 405 nm Violet laser and collected using a 780/60 bandpass filter. BV750 has an excitation peak at 405 nm and an emission peak at 786 nm. Due to its unique Stokes shift, few dyes have identical or near identical excitation and emission spectrums, but the nearest alternatives are Qdot® 800 and SuperBright 780 (ThermoFisher), and Brilliant™ Violet 785 (BioLegend). What's the difference between BV785 and BV786? BV785 is a BioLegend color, while BV786 is a BD Biosciences color, but they exhibit the same spectral properties. This dye exhibits a medium level of brightness and is most often used in flow cytometry. Older instruments may not be set up for a dye with such a large Stokes shift, however BV786 is especially well suited for spectral cytometers or sorters. 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.
