CRISPR DETECT
GRNA DETECTION WITH GENE EXPRESSION

A new era of single cell CRISPR screens

Single cell pooled CRISPR screens enable analysis of complex phenotypes by linking individual gene perturbations with gene expression profiles. This approach has been used for target validation in drug discovery, to understand differences in treatment responses, and map pathways involved in cell differentiation. Wider adoption of this approach has been constrained by the feasibility and high cost of processing sufficient cells for libraries containing more than a few hundred guide RNAs (sgRNAs). CRISPR Detect brings the scalability of Evercode™ technology to single cell CRISPR screens, making genome-wide studies practical.

More perturbations with fewer runs

Scale easily with CRISPR Detect and Evercode™ Whole Transcriptome kits.

Number of runs in recently published CRISPR screens

The published number of 10x Genomics Chromium Next GEM Single 3’ Kit lanes and projected Evercode™ Whole Transcriptome kits to obtain the same number of cells.

Sensitive guide detection

Avoid wasted sequencing and underpowered studies.

High-guide RNA detection with low background

LN18‭ ‬cells were prepared to only express one sgRNA then analyzed with Evercode™ WT Mega v2 and CRISPR Detect.

The CRISPR Detect workflow

CRISPR Detect is a powerful addition to Evercode™ Whole Transcriptome capabilities and seamlessly integrates into the same workflow.

1
Evercode™ Cell/Nuclei Fixation

Lock in gene expression immediately after sample collection with a rapid fixation protocol. After fixation, samples can be stored for up to 6 months or proceed directly to barcoding.

2
Evercode™ Whole Transcriptome

Append barcodes to each transcript by progressing cells through split-pool combinatorial barcoding, then proceed for library preparation.

3
CRISPR Detect

CRISPR Detect pairs with Evercode™ Whole Transcriptome to enrich sgRNA sequences.

4
Sequencing

Evercode™ Whole Transcriptome and CRISPR Detect libraries are sequenced together.

5
Analysis

A computational pipeline generates an interactive report for rapid insights. All output data files, including gene-cell count matrix, integrate seamlessly with existing open source tools such as Seurat or Scanpy.
