lifescience-BD-AbseqBD (Becton, Dickinson and Company) (NYSE: BDX), a leading global medical technology company, today announced the commercial release of the BD® AbSeq assay to analyze protein expression at the single-cell level using high-throughput sequencing. The assay brings together high-quality antibodies from the BD Pharmingen™ portfolio with oligonucleotides, allowing researchers to perform single-cell protein analysis on the BD Rhapsody™ single-cell analysis system. When used together, these research tools enable researchers to simultaneously analyze RNA and proteins in thousands of individual cells and develop a more complete picture of the role genes and proteins play in biological systems.

The product leverages 40 years of BD leadership in immunology research. Initially available with more than 100 different human antibody-oligonucleotide combinations, over time BD will rapidly expand the portfolio to utilize its vast library of flow cytometry-proven human and mouse antibody clones, helping researchers to advance understanding of complex diseases. Customers can also design their own custom conjugates. 

To advance knowledge of the immune system, BD empowers immunology researchers with a range of tools for multi-omics analysis. The launch of the BD® AbSeq assay is the latest innovation in BD’s single cell multi-omics portfolio. Over the last year, BD has built on its BD Rhapsody™ single-cell analysis system, a complete system of reagents, instruments, software, and targeted gene panels, to offer additional single-cell analysis capabilities. These include the BD Rhapsody™ Express system and the BD™ single-cell multiplexing kit. These new offerings provide targeted RNA-seq options and enable sample pooling to improve data quality and reduce time to discovery.
