TotalSeq™ Reagents for Single-Cell Proteogenomics

TotalSeq™ oligo-conjugated antibodies enable measurement of proteins at a single cell level and integrate seamlessly into existing single-cell RNA sequencing workflows, including Drop-Seq and those available from 10x Genomics.

Simultaneous Multiomic Data Generation: Increase the power of single cell experiments by combining proteomic and transcriptomic data.

Reduced Dropouts: In contrast to mRNA, TotalSeq™-derived antibody tags are not highly prone to dropouts, which are essentially false negative readouts.

Ultra-High Parameter Protein Detection: Detect hundreds of proteins in a single cell.  A lower dropout rate contributes to enhanced sample clustering and the ability to better identify specific cell types.

Diverse applications: With a wide-range of mouse and human targets available, you can use TotalSeq™ antibodies in a variety of research areas, including:

Buyer is solely responsible for determining whether Buyer has all intellectual property rights that are necessary for Buyer's intended uses of the BioLegend TotalSeq™ products. For example, for any technology platform Buyer uses with TotalSeq™, it is Buyer's sole responsibility to determine whether it has all necessary third party intellectual property rights to use that platform and TotalSeq™ with that platform.

This technology was first described by Stoeckius et al. of the NY Genome Center as they used antibodies coupled with oligonucleotides to simultaneously measure proteins and RNA at a single-cell level. They termed this method Cellular Indexing of Transcriptomes and Epitopes by sequencing or CITE-seq. Learn more about CITE-Seq and other TotalSeq™ applications in one of our webinars.
