The 50C1 monoclonal antibody specifically binds to human CD371 which is also known as Clec12A (C-type lectin domain family 12 member A), C-type lectin-like molecule 1 (CLL-1), myeloid inhibitory C-type lectin-like receptor (MICL), or dendritic cell-associated lectin 2 (DCAL-2). It is expressed on a variety of cells including monocytes, macrophages, dendritic cells, and granulocytes and perhaps some NK cells. Clec12A is a member of the C-type lectin/C-type lectin-like domain (CTL/CTLD) superfamily. It is a 30 kDa type II transmembrane glycoprotein that has one single C-type lectin-like domain and one cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM). Clec12A has similarity with the β-glucan receptor (Dectin-1) and LOX-1 with high N-glycosylation. There are at least five isoforms due to alternative transcript splicing. Signaling through Clec12A can induce internalization of Clec12A, dendritic cell maturation and the production of cytokines including IL-12. Clec12A may also serve as a negative regulator of activated leukocytes recruited to sites of inflammation.
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.
