To facilitate scalable profiling of single cells, engineers at the University of Washington have developed split-pool ligation-based transcriptome sequencing (SPLiT-seq), a single-cell RNA-seq (scRNA-seq) method that labels the cellular origin of RNA through combinatorial barcoding. SPLiT-seq is compatible with fixed ...

Bioinformatics publications typically include complex software workflows that are difficult to describe in a manuscript. University of Washington, Tacoma researchers describe and demonstrate the use of interactive software notebooks to document and distribute bioinformatics research. They provide a user-friendly tool, ...

To resolve cellular heterogeneity, researchers from the University of Washington developed a combinatorial indexing strategy to profile the transcriptomes of single cells or nuclei, termed sci-RNA-seq (single-cell combinatorial indexing RNA sequencing). They applied sci-RNA-seq to profile nearly 50,000 cells from ...

Single cell RNA-seq (scRNA-seq) experiments can provide a wealth of information about heterogeneous, multi-cellular systems. However, this information has to be inferred computationally from sequencing reads which constitute a sparse and noisy sub-sampling of the actual cellular transcriptomes. Here, University ...

RNA-Seq has supplanted microarrays as the preferred method of transcriptome-wide identification of differentially expressed genes. However, RNA-Seq analysis is still rapidly evolving, with a large number of tools available for each of the three major processing steps: read alignment, expression ...
Read More »Census – Single-cell mRNA quantification and differential analysis
Single-cell gene expression studies promise to reveal rare cell types and cryptic states, but the high variability of single-cell RNA-seq measurements frustrates efforts to assay transcriptional differences between cells. University of Washington researchers have developed the Census algorithm to convert ...

RNA-Seq has supplanted microarrays as the preferred method of transcriptome-wide identification of differentially expressed genes. However, RNA-Seq analysis is still rapidly evolving, with a large number of tools available for each of the three major processing steps: read alignment, expression ...
Read More »Isolator – accurate and stable analysis of isoform-level expression in RNA-Seq experiments
While RNA-Seq has enabled great progress towards the goal of wide-scale isoform-level mRNA quantification, short reads have limitations when resolving complex or similar sets of isoforms. As a result, estimates of isoform abundance carry far more uncertainty than those made ...
Read More »Detecting Sources of Transcriptional Heterogeneity in Large-Scale RNA-Seq Data Sets
Gene expression levels are dynamic molecular phenotypes that respond to biological, environmental, and technical perturbations. Here, University of Washington researchers use a novel replicate classifier approach for discovering transcriptional signatures and apply it to the Genotype-Tissue Expression (GTEx) data set. ...
