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.

Explore Applications

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.

Analyze Data

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.

Expand Bulk Sequencing

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.
