CRISPR Cas9 Lentiviral Guide RNA Libraries with expressed barcodes for RNA-Seq / Perturb-Seq
CloneTracker XP™ Lentiviral CRISPR Clonal Barcode Libraries
• Custom and Off-the-shelf (mouse and human) CRISPR Barcode Libraries with expressed barcoded sgRNA expression cassette that can be detected using RNA-Seq assays
• Use with drop-seq single cell platforms for single-cell CRISPR screens (known as Perturb-Seq, or CRISPR‑Seq).
Pooled CRISPR screening with lentiviral sgRNA libraries has proven to be a very effective approach to identify genes functionally required to generate particular phenotypes, and RNA-seq to be an effective method to find the underlying changes in gene expression producing those phenotypes. With the advent of droplet microfluidic platforms that enable single cell molecular analysis on a large scale, these two technologies can be merged to assess and characterize the distinct expression profiles produced by genetic disruption in a pooled CRISPR knockout screen. With this sort of pooled screening approach using CRISPR barcode libraries, isolation and characterization of phenotype-specific cells is unnecessary.
CloneTracker XP CRISPR Barcode Libraries express an sgRNA for pooled CRISPR genetic screens with a unique molecular identifier (UMI or barcode) that facilitates clonal cell tracking and single-cell expression analysis. In these libraries, the barcoded sgRNA expression cassette is positioned so that it is on the 3′-non-coding region of the puromycin selection gene and present on the polyA+ when this gene is expressed. As a result, the sgRNA and barcode can be detected in the RNA Expression data. When combined with single cell expression profiling, changes in gene expression can be directly correlated to gene knockout, knockdown, or activation, depending on the type of CRISPR construct used to make the library.
Cell-specific barcodes incorporated into pooled CRISPR sgRNA libraries can be used in conjunction with single-cell RNA expression analysis to perform Perturb-Seq / CRISPR-Seq screens. The approach enables researchers to reliably identify and link changes in gene expression to the knockout of particular target genes.
Cellecta currently offers 2 complementary premade CloneTracker XP CRISPR Knockout libraries, one targeting 27 human anti-cancer genes and one targeting the 27 corresponding mouse homologs. There are 20 sgRNAs to each gene designed to target functional domains.
20 Non-Targeting sgRNA are included as controls.
