Immune phenotypic analysis using predesigned and lyophilized BD (R) AbSeq Immune Discovery Panel

Abstract High-throughput single cell RNA sequencing (scRNA-seq) has recently emerged as a powerful tool for profiling complex cell populations. While traditional scRNA-seq captures information at the transcript level, recent technology using DNA-barcoded antibodies enable multiomic analysis, examining protein alongside mRNA. Although this approach allows analyzing a large number of protein markers, the sequencing cost can escalate quickly for large panels, particularly ones with high antigen-density markers, and workflows can be long. Therefore, panels should be optimized to gain meaningful results efficiently and cost-effectively. Here, we introduce the BD® AbSeq Immune Discovery Panel (IDP), a lyophilized panel consisting of 30 antibodies against major human immune cell-types and immune response markers for analyzing multiple immune cell subsets. The BD® AbSeq IDP can be used to uncover phenotypic changes in cell subsets such as unique cell input differences or changes in the immune cell status. To test this capability, we used the IDP alongside a mRNA analysis using targeted mRNA panel and whole transcriptome assay to compare the immune phenotypes of cells from disease and in vitro stimulated samples at the single-cell level using the BD Rhapsody™ System. We propose that the BD® AbSeq IDP can be used to identify the cell types and molecular pathways impacted by the disease at the single cell level. For Research Use Only.
