Functional Genomic Screening

Identify Targets Others Miss

Functional genomic screens enable the modulation of hundreds or thousands of genes in a single experiment to identify genetic pathways, cellular processes, novel therapeutic targets, and to genetically profile existing or potential therapeutics.

Revvity’s wide range of gene editing and modulation solutions are designed to support you in every step of your workflow. From CRISPR and RNAi libraries for high-throughput functional genomic screening to automated image platforms and cellular assays, we offer all the tools and technologies to help you edit with confidence and maximize your chance of success.

Building on Dharmacon's 30-years of experience in gene editing and modulation, we support customers to choose the best reagent and analysis technologies to achieve the desired results. Revvity can empower and partner with you to find the best solutions for your own research or our team of scientific experts can provide functional genomics screen as service.

Functional Genomic Workflows

Gene expression can be regulated using either RNAi or CRISPR technology, where RNAi represses gene expression at the mRNA level (knockdown), while CRISPR works at the DNA level and can permanently knockout, modulate, or knock-in genes.

The pivotal aim of a functional genomic screen is to elucidate the correlation between genotype and phenotype on a genome-wide scale. There are two main approaches how to perform gene editing/modulation and asses the resulting phenotypic response pooled and arrayed. Explore here how they work.

Pooled Screens Arrayed Screens
Pooled screening: whereby editing is performed with a mixture of guide RNA (gRNA) and thus a high number of perturbations occur. The mixed cell population is then exposed to a treatment and analysed by NGS for deconvolution with an optional sorting step before. This approach is very cost effective, however only macro effects can be detected. Learn More. Arrayed screens: where each CRISPR-based perturbation occurs in a separate well of a multi-well plate, offering a clear phenotype to genotype correlation. The main read-out is imaging, which could be combined with detection or sequencing enabling a multi-parametric analysis. They are also well-suited for more advanced cell models like primary cells or 3D cell cultures. Learn More.

Explore by Application 

CRISPR has exploded within the scientific research community and contributed to many notable breakthroughs. With a ride range of important applications, the technology has become pivotal for research and beyond. 

arrow Disease Models
  • Use CRISPR knockout, CRISPR activation, and CRISPR interference to understand specific gene contribution to a disease
  • Use gene knock-in to insert mutations mimicking disease or wild-type biology for better validated targets or compound identification
arrow Pathway Analysis
  • Understand the function of genes and how they contribute to biological processes and diseases
arrow Target Identification
  • Identify relevant targets or hits from phenotypic screening
  • Assess the contribution of each gene in the genome to compound activity in a full genome loss-of-function screen
arrow Target Validation
  • Verify targets in an arrayed secondary screen (smaller set of genes) and eliminate false positives
  • Investigate gene knockout or modification in a variety of cell types to determine if a gene target provides the same phenotype in multiple cell types

The Various Types of CRISPR


Explore our CRISPR Workflows Solutions

Gene Editing Reagents

Selecting the appropriate format of CRISPR reagents is the first critical step before starting a screen. We offer a variety of formats, so that regardless of the scientific question, we can support your experimental needs.

Cas9 nuclease

Cas9 nuclease reagents are available as Cas9 protein, mRNA, plasmid, or lentiviral Cas9. For optimization and enrichment, versions co-expressing a fluorescent tag are available.


Edit-R ™ CRISPR guide RNA are available in pools or as individual reagents, as predefined CRISPR knockout libraries, or a library can be designed using the cherry-pick library tool.

Homology-directed Repair Knock-in templates

HDR relies on the presence of a donor template with sufficient homology to the regions flanking the cut site. The homology arms’ length and donor type will depend on the modification being made. Our templates make it easy to customize a donor oligo.

Transfection and ancillary reagents

Successful introduction of gRNA and Cas9 protein into the cell is key to any gene-editing experiment to ensure efficiency. Our range of transfection reagents provide efficient and reliable delivery of CRISPR gRNA with minimal cellular toxicity.

Sample Prep & Automation

These types of assays are often labor intensive and require many steps for re-suspending the CRISPR reagents, cell transfer, and treatment addition or staining. To accelerate your assay, we offer a full range of liquid handling, integrated laboratory automation, and cell counters that together with our specially designed microplates, improve your workflow and provide consistent and quality results.
