TotalSeq™ and Comprehensive Multiomics Solutions

news February 16 2021


Multiomics has transformed traditional sequencing experiments by providing unparalleled protein and genetic analysis on a single-cell or bulk sequencing basis. BioLegend offers comprehensive and unique products, including antibodies, panels, and hashtag reagents to enable protein detection by sequencing. Explore the capabilities of TotalSeq™ reagents and see how they integrate seamlessly into existing workflows, enabling to simultaneously analyze protein and RNA expression on a single cell level.

TotalSeq™ oligo-conjugated reagents enable protein detection by sequencing and integrate seamlessly into existing single-cell transcriptomics, bulk sequencing, or single-cell genomics workflows. Choose your experimental goal below and discover BioLegend`s comprehensive solutions for single-cell and bulk multiomics.

Single-Cell RNA and Protein Detection – Compatible with TotalSeq™-A, TotalSeq™-B and TotalSeq™-C reagents

Technologies like CITE-seq and REAP-seq utilize oligonucleotide-conjugated antibodies to simultaneously detect surface proteins and RNA. For this, we offer multiple formats of BioLegend`s TotalSeq™ antibodies, panels, and hashtags to incorporate into single-cell transcriptomics workflows, including Drop-Seq and those offered by 10x Genomics.

Hashtag Reagents

Bulk RNA Sequencing – Compatible with TotalSeq™-A reagents

Bulk RNA-sequencing is commonly used to analyze RNA expression from a population of cells in suspension. BioLegend`s BEN-seq workflow, developed in collaboration with Illumina, stains cells in suspension with TotalSeq™ oligo-conjugated antibodies prior to bulk RNA sequencing, enabling the simultaneous profiling of cell surface proteins and RNA expression.

Multiomics Analysis Software – For single-cell RNA and protein data analysis

Processing and analysis of single-cell data can be complicated and require advanced tools. To simplify the process, BioLegend offers Multiomics Analysis Software (MAS), a free cloud-based program for the analysis of multiomics data. Featuring an intuitive user interface with flow cytometry-like gating, the software is accessible to all users irrespective of their bioinformatics background.

Uncovering SARS-CoV-2 Specific Cells and Biomarkers

TotalSeq™ reagents can be used to enable:

  • Multiomic analysis (Protein + RNA) of immune cells and lung alveolar lavage in COVID-19 patients (TotalSeq™-A or B in combination with 10x Genomics Single Cell Expression Solution (3’ assay)).
  • TCR/BCR repertoire profiling in COVID-19 patients for immunotherapy and vaccine development (TotalSeq™-C with 10x Genomics Immune Profiling Solution (5’ assay)).

The TotalSeq™-C Human Universal Cocktail, V1.0 was recently used for single-cell multiomic analysis in the paper by Su et al. and revealed unique immune cell subpopulations in COVID-19 patients. The TotalSeq™-C Human Universal Cocktail, V1.0 is available as a ready-to-use cocktail with 130 markers and 7 isotype control antibodies.
