Performance of Immune1000 Gene Select in Human Immune Cells (PBMCs)

Key takeaways

• High resolution and cell type proportion after enrichment
• >10 times less sequencing required
• High on-target rate (>80%) with Gene Select

High resolution data with less sequencing

Evercode WT libraries and the same libraries enriched with Immune1000 Gene Select showed similar clustering resolution, and cell type proportion with >10 times less sequencing depth. The Immune1000 Panel contains probes designed to enrich for immune cell type markers and pathways.

Immune1000 Panel was used to enrich 8 sublibraries from an Evercode WT kit. Libraries were then sequenced at 2,000 reads/cell, yielding an on-target rate of >80%. When compared to the non-enriched libraries sequenced at 28,000 reads/cell, the Immune1000 panel showed the same cell type clustering as the whole transcriptome.

Figure 1. Cell type clustering in non-enriched and enriched libraries. Whole transcriptome libraries were prepared from human peripheral blood mononuclear cells (PBMC) obtained from 2 donors. Immune1000 captured immune specific genes from 105,462 cells across 8 sublibraries.

Concordant cell types

A correlation plot produced unbiased concordance of immune cell types from 2 donors in libraries prepared with Evercode WT and enriched with Immune1000 Gene Capture (r2=0.998).

Figure 2. Cell Type proportions are retained. Evercode WT libraries with and without Immune1000 Gene Capture show a nearly perfect concordance of cell types. Each dot corresponds to an immune cell type.
