Compare and contrast the features of a wide variety of guide RNA (gRNA) and Cas9 products for in vitro and in vivo CRISPR experiments. Select the best formats for your mammalian or plant applications: SygRNA ® synthetic gRNA, plasmid DNA, lentiviral particles, and proteins.

Exclusive human or mouse whole genome arrayed libraries developed with the Wellcome Sanger institute

Pooled CRISPR screening with 10x Genomics compatibility

The Gator ® AAV9 Probes are high specificity nanobody-based biosensors that enable direct capture and quantitation of AAV9 in crude lysates, column eluates, cell lysates and cell culture supernatants. The Gator ® AAV9 probe uses proven CaptureSelect™ (Thermo Fisher Scientific) high affinity and high specificity anti-AAV9 nanobody.

The 10x Compatible Human CRISPRi Kinase Phosphatase Drug Targets Kit (Druggable Genome) contains one sub-pool of the top two ranked sgRNAs per gene for increased sensitivity and includes non-targeting controls built-in.

The Human CRISPR activation library (Calabrese) activates over 18,000 human genes and is used for genome-wide activation screening. The library is designed to be compact and efficient to maximize screening efficiency and performance, as published by Sanson, K.R., et al. Nat Commun 9, 5416 (2018).

The mouse CRISPR activation library (Caprano) activates over 22,000 mouse genes and is used for genome-wide activation screening.

Design gRNA or search pre-designed guides

The control kit includes validated positive control targeting RAB1A and non-targeting control for assay set-up and a UCOE KRAB-dCas9 for consistent effector expression across a wide variety of cell lines. The kit is ideal for setting up the screen assay and optimization before using the CRISPRi library pools.

The 10X CRISPRi Feature Barcode Optimization kit is ideally suited for setting up the screen assay and if desired capture sequence optimization before using the Custom 10x Compatible CRISPRi library pools.

This pooled library targets the human kinome, a collection of approximately 700 genes commonly associated with development and disease, with an average of nearly 9 unique knockout CRISPR clones per kinase gene. The lentiviral format allows for stable integration, selection, and enrichment of transduced cells
