The 16.1 monoclonal antibody recognizes the C57BL/6 mouse CD161a, CD161b, and CD161c (CD161a, b, c) cell surface molecules, which are also known as Natural killer cell receptor P1A (NKRP1A), NKRP1D, and NKRP1C, respectively. These cell surface molecules are expressed by natural killer (NK) cells and may play a role in NK cell functions. The 16.1 antibody does not crossreact with CD161f (NKRP1F). This antibody likely binds to CD161 molecules expressed by lymphoid cells from some other mouse strains.
This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.
