The UC3-10A6 monoclonal antibody specifically recognizes T-cell Receptor (TCR) V gamma 2 (Vγ2). Vγ2+ TCRγδ cells make up significant proportions of TCRγδ cells in the late fetal and adult thymus and adult peripheral lymphoid tissues and lung. The frequency of splenic Vγ2+ TCRγδ cells differs among inbred mouse strains; in C57BL/6 mice, the frequency increases dramatically during the four weeks after birth. Immobilized UC3-10A6 antibody can activate Vγ2+ TCRγδ cells. Please note that the Vγ2 designation correlates with the nomenclature of Garman, Doherty, and Raulet; the Vγ4 designation of Heiligand Tonegawa is equilvalent.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
