The p30-15 monoclonal antibody specifically binds to CD337, also known as NKp30, a receptor found on the surface of natural killer (NK) cells. NK cells are large lymphoid cells discovered because of their ability to recognize and kill abnormal cells such as tumor and virally infected cells. NK cell immune responses are regulated by a balance of activating and inhibitory signals generated by cell surface receptors. Inhibitory receptors recognize MHC class I molecules on normal cells producing a negative signal to the NK cell. Loss of MHC class I expression in infected or transformed cells results in the loss of this negative signal leading to NK cell activation. In concert with the loss of inhibitory signals, activation signals via NK receptors such as NKp30, NKp44, NKp46, NKG2D, and NKp80 mediate the activation of NK cells. NKp30 cooperates with NKp46 and/or NKp44 in the induction of NK cell-mediated cytotoxicity against the majority of target cells.
The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 786-nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
