Vivlion’s proprietary PRCISRTM CRISPR technology enables next generation CRISPR screening. For the preparation of gRNA libraries, the technology avoids PCR-amplification of oligo pools as well as restriction and ligation-based cloning, thereby overcoming the major challenges in the generation of conventional libraries. In addition, it decouples sequence diversity and sequence distribution, resulting in uniformly distributed libraries.

Superior performance

PRCISRTM CRISPR libraries have gRNA representation of exceptional uniformity (skew < 2) in order to identify all targets. The libraries are strictly quality-controlled by NGS.

Unlimited diversity

PRCISRTM CRISPR libraries can be made in any diversity without compromising on reagent quality. Both single and dual-combinatorial gRNA library formats are available.

Maximized efficiency

PRCISRTM CRISPR libraries downscale experimental size (x10), delivering optimum results with significantly less library coverage and cell culture material, saving time and costs.

 Uniformity matters!

The heterogeneity problem

Uniformity matters! A genome-wide pooled CRISPR/Cas screen, with each gene targeted by 2 gRNAs, contains more than 40.000 gRNAs. If these gRNAs are not evenly distributed in the pool, then you will face the following challenges:

  • Low data quality: During the screen, bias is introduced in gene editing events – this leads to errors in the identification of enriched or depleted genes, which in turn severely impacts on the reliability of the screening data. In the worst case, you will miss out on promising true targets whilst obtaining false positives.
  • Prohibitive experimental size: To maintain statistical power, the screening experiments may need to be excessive in size. The higher the library skew, the larger the experimental setup needed to obtain valid results.

Vivlion’s PRCISR™ CRISPR technology enables uniformly distributed libraries by removing PCR and conventional cloning techniques during production. PRCISR™ CRISPR libraries are evenly distributed enabling minimized experimental setup and robust data quality.
