The LS132.1D9 (aka, 1D9) monoclonal antibody specifically recognizes C-C chemokine receptor type 2 (CCR2 or CC-CKR-2) which is also known as CD192, CKR2, CMKBR2, or Monocyte chemoattractant protein 1 receptor (MCP-1 Receptor or MCP-1-R). CCR2 (CD192) is a seven-transmembrane, G-protein-coupled, glycoprotein receptor that belongs to the beta chemokine receptor family. It is expressed on basophils, monocytes/macrophages, dendritic cells, activated T cells and B cells. CCR2 (CD192) serves as a receptor for Monocyte chemoattractant protein 1 (MCP-1/CCL2), MCP-2/CCL8, MCP-3/CCL7, and MCP-4/CCL13. CD192 exists in two forms, CD192A and CD192B. The two forms are derived from alternatively spliced variants of a single gene and differ at their intracellular C-terminal ends. CD192 plays an important role in inflammatory responses including monocytic infiltration of tissues associated with certain diseases, eg, atherosclerosis, rheumatoid arthritis, and tumors.
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.
