Comprehensive Solutions for Single-Cell and Bulk Multiomics


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 our solutions.


If you can’t find the reagents you’re looking for, contact us to discuss your project. We offer custom oligo-conjugated reagents including individual antibodies and cocktails. Let us know how we can support your multiomics work.

Single-Cell RNA and Protein Detection

Compatible with TotalSeq™-A, B, and 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 our TotalSeq™ antibodies, panels, and hashtags to incorporate into single-cell transcriptomics workflows, including Drop-Seq and those offered by 10x Genomics.


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.


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. Our 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.


Single-Cell DNA and Protein Detection

Compatible with TotalSeq™-D reagents.


Resolve complex genetic questions from genotype to phenotype by combining single-cell DNA analysis with protein detection using TotalSeq™-D oligo-conjugated reagents. Our TotalSeq™-D antibodies and cocktails are constructed for compatibility with the Mission Bio Tapestri platform to enable the co-detection of SNVs/indels, CNVs, and proteins.
