About CD11b
This gene encodes the integrin alpha M chain. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This I-domain containing alpha integrin combines with the beta 2 chain (ITGB2) to form a leukocyte-specific integrin referred to as macrophage receptor 1 ('Mac-1'), or inactivated-C3b (iC3b) receptor 3 ('CR3'). The alpha M beta 2 integrin is important in the adherence of neutrophils and monocytes to stimulated endothelium, and also in the phagocytosis of complement coated particles. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

About RealYellow 586
BD Horizon RealYellow 586 (RY586) is a bright, yellow emitting dye used in flow cytometry. This fluorophore is excited optimally by the 561 laser and is similar in its emission properties to PE, but interestingly, RY586 shows minimal cross-laser excitation with the 488 laser and can be used in spectral flow cytometry panels concurrently with PE (as stated by supplier).
