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 an oligonucleotide that contains an antibody clone-specific barcode (ABC) flanked by a poly-A tail on the 3' end and a PCR handle (PCR primer binding site) on the 5' end. The ABC for this antibody was designed to be used with other BD AbSeq oligonucleotides conjugated to other antibodies. All AbSeq ABC sequences were selected in silico to be unique from human and mouse genomes, have low predicted secondary structure, and have high Hamming distance within the BD AbSeq portfolio, to allow for sequencing error correction and unique mapping. The poly-A tail of the oligonucleotide allows the ABC to be captured by the BD Rhapsody™ system. The 5' PCR handle allows for efficient sequencing library generation for Illumina sequencing platforms.
NOTE: The BD Rhapsody Single-Cell Analysis System must be used with the BD Rhapsody Express Instrument.
