The KPL-1 monoclonal antibody specifically binds to p-selectin glycoprotein ligand-1 (PSGL-1), a 120-220 kDa, mucin-like type I transmembrane glycoprotein. CD162 is expressed on neutrophils, monocytes, and most lymphocytes. CD162 binds to CD62P (P-Selectin), CD62E (E-Selectin) and CD62L (L-Selectin). This molecule mediates rolling of leukocytes on activated endothelium and the interaction between leukocytes and activated platelets or other leukocytes found at inflammatory sites. It has also been reported that this clone completely inhibits the interaction between P-Selectin and either CD4-T cells or neutrophils.
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.
