The Neu 24.7 monoclonal antibody specifically recognizes HER-2/neu, which is also known as p185HER2 or CD340. HER-2/neu is a ~185 kDa type I transmembrane glycoprotein that is encoded by ERBB2 (erb-b2 receptor tyrosine kinase 2) which belongs to the ERBB receptor kinase family. The HER-2/neu antigen is expressed on some breast cancer cells. Amplification and/or over expression of HER-2/neu occurs in multiple human malignancies. Overexpression is reported to be strongly correlated with progression of human ovarian and breast carcinomas. Anti-HER-2/neu stains the external domain of this protein on cells such as the strongly expressing line SKBR3 and the weakly expressing line MCF7. HER-2/neu is also expressed on normal bone marrow mesenchymal stem cells (MSC).
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.
