General description

Two leaders in genome editing, Sigma-Aldrich and the Wellcome Trust Sanger Institute, have joined forces to make the first ever arrayed lentiviral CRISPR knockout libraries. Based upon validated techniques published in the literature, the Sanger CRISPR libraries will put your lab at the forefront of the race to make the next big discovery.


Functional Genomics/Screening /Target Validation

Features and Benefits

  • Vector: U6-gRNA/PGK-Puro-2A-BFP (gRNA only)
  • Simplify the workflow with puromycin selection
  • Illuminate CRISPR-expressing cells with BFP

Additional Features
  • Better, not bigger: Two optimized clones per gene reduces the time, cost, and scale of screening experiments
  • Ready-to-screen: Clones are arrayed in a robotics-friendly 384-well format for high throughput screening
  • Collaborative: Real-time, library validation continues

Physical form

10 μl of lentivirus at ≥106 particles/ml in 102×384-well plates

Other Notes

This product is for R&D use only, not for drug, household, or other uses. Lentivirus manufacturing is achieved by using 2nd generation packaging plasmids on a 3rd generation lenti-based vector. Though the lentiviral transduction particles produced are replication incompetent, it is recommended that they be treated as Risk Group Level 2 (RGL-2) organisms in laboratory handling. Follow all published RGL-2 guidelines for laboratory handling and waste decontamination.

This screening guide covers how to choose a cell line, a screening library, and experimental conditions as well as tips for designing and performing your experiment.

Genome-wide loss-of-function screening is a powerful approach to discover genes and pathways that underlie biological processes. Now complete knockout is achievable with two optimized gRNAs per gene. Minimized clone number ensures the most specific screening possible while controlling time and cost.

Get tips for handling lentiviruses, optimizing experiment setup, titering lentivirus particles, and selecting helpful products for transduction.


Learn about Sanger Sequencing steps or the chain termination method and how DNA sequencing works and how to read Sanger Sequencing results accurately for your research.

FACS (Fluorescence-Activated Cell Sorting) provides a method for sorting a mixed population of cells into two or more groups, one cell at a time, based on the specific light scattering and fluorescence of each cell. This method provides fast, objective, and quantitative recording of fluorescent signals from individual cells.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
