The 2.11 monoclonal antibody recognizes the Vγ1.1 chain of the heterodimeric γδ T-cell receptor (TCR γδ) expressed by T lymphocytes and NK-T cells. It does not react with TCR αβ-bearing T cells. TCR γδ associates with CD3 molecules to form the TCR γδ/CD3 complex that mediates antigen recognition and can transduce intracellular signals leading to T cell responses. The Vγ1.1 TCR is also known as Vγ1 TCR. The Vγ1.1 variable region TCR gene segment primarily rearranges to join the Jγ4 and Cγ4 TCR gene segments. TCR Vγ1-expressing cells represent a major population of TCR γδ cells in the adult mouse thymus, peripheral lymphoid tissues, and different epithelia. They constitute a minor population of TCR γδ-positive T cells during fetal and early postnatal life.
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.
