The B6 monoclonal antibody specifically recognizes the human variable δ2 subunit (Vδ2) of the γ/δ T cell receptor (TCR). The γ/δ TCR is composed of two disulfide linked glycoproteins. The delta chain is approximately 40-60 kDa and is restricted to peripheral blood T cells and thymocytes. The majority of normal peripheral blood γ/δ T cells express a Vγ9[+]/ Vδ2[+] phenotype. The reason for this selection in the T-cell repertoire is not well understood.
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.
