Horizon Discovery introduces single-cell RNAseq-linked CRISPR screening service
4 Aug 2020
Horizon Discovery has announced the addition of single-cell RNAseq-linked pooled CRISPR screening to its CRISPR screening services portfolio. The platform offers high-quality screening data and biological insight to address critical gaps in target identification and validation.
This launch is the result of a collaboration, announced in 2018, to develop and apply this novel research tool to discover new biology essential for the development of future therapeutics. The biological insight gained from Horizon’s single-cell RNAseq-linked CRISPR screening platform could help researchers to gain further understanding into complex biological models and speed up the time from discovery to validation by integrating the effect of gene editing with complex gene expression mapping.
Horizon’s pooled format screens offer researchers access to highly robust whole-genome level analyses that yield quality data outputs. Currently, it can be challenging to adequately multiplex the data from these screens to evaluate complex biological phenomena occurring in a subset of edited cells. Coupling pooled CRISPR screening to single-cell RNAseq allows the impact of CRISPR-based gene modification to be examined on a global transcriptomic scale at single-cell resolution. This could enable scientists to address critical gaps in target identification and validation as they work to develop new and more effective therapeutics.
“Pooled CRISPR-Cas9 knockout screens have become a linchpin in drug target identification and validation. The development of our single-cell RNAseq-linked pooled CRISPR screening service provides a substantial advance to Horizon’s screening capabilities,” said Terry Pizzie, Chief Executive Officer, Horizon Discovery. “Our continuing development of cutting-edge services, including CRISPR screens in primary human immune cells, means we can offer our customers unparalleled insights into the biology that will help to underpin future drug and cell-based therapeutics.”

CRISPR Screening Services
CRISPR Screening Services Horizon offers comprehensive CRISPR screening services from screen design and cell line selection to sophisticated bioinformatics analysis of the screen results. Our best-in-class CRISPR KO (knockout), CRISPRi (interference) and CRISPRa (activation) screening platforms can significantly advance our customers’ drug development programs by offering the highest quality and highest confidence in their screening results. Data analysis services, including sample preparation, Next-Gen Sequencing, and hit calling, can be provided for users of Edit-R Lentiviral sgRNA Pooled Screening Libraries. Simply provide whole cell pellets for each of your samples and we’ll do the rest. We can also help with the NGS data analysis and hit calling for data created using the Edit-R Pooled sgRNA Indexing PCR and Sequencing Primer Kits. Types of CRISPR Screen Expertise includes whole-genome and custom targeted drug resistance and sensitivity screens, synthetic lethality target discovery screens and complex phenotypic screens using a FACS-based readout. We have optimized 50+ cell lines for CRISPR screening and have completed over 300 screens to date. We offer a choice of CRISPR screen types depending on the expression effect you require: CRISPR KO screening with complete loss of gene expression provides the maximal window for phenotypic effect and high statistical power for hit discovery CRISPRi screening represses expression rather than completely knocking out the target gene and is ideally suited to study druggability and to evaluate the function of genes that when knocked-out are essential or that are amplified CRISPRa screening amplifies gene expression in its endogenous context and enables for the first time, to study activation-linked responses on a genome-wide level Dual CRISPRi & CRISPRa screening
