Leveraging Ubigene CRISPR Library Cell Pools for High-Throughput Functional Genomics

In recent years, CRISPR/Cas9 technology has revolutionized functional genomics, providing researchers with a robust platform to interrogate gene function systematically across the genome. As the demand for high-throughput, reliable, and reproducible screening systems increases, Ubigene has developed CRISPR Library Cell Pools, powered by proprietary CRISPR iScreen™ technology, to meet the needs of modern genomic research. These screening-ready cell pools combine the power of Cas9-mediated genome editing with comprehensive guide RNA (gRNA) libraries, enabling researchers to explore gene function under a wide range of biological contexts.

Ubigene CRISPR Library Cell Pools are collections of mammalian cells that are stably engineered to express the Cas9 nuclease along with a curated library of gRNAs. Each pool is designed for either genome-wide knockout studies or focused gene-targeted investigations, providing a versatile platform for both broad and hypothesis-driven functional screens. These cell pools are particularly valuable for high-throughput genetic screens, enabling the identification of genes involved in disease mechanisms, drug responses, or cellular stress adaptation.

1. High-Quality Content

Each cell pool is generated from a high-coverage gRNA library, ensuring comprehensive representation of target genes. Ubigene employs rigorous next-generation sequencing (NGS) and quality control procedures to verify library composition, uniformity, and coverage. This attention to detail ensures that every batch of cell pools maintains a high level of consistency, minimizing experimental variability and enhancing reproducibility.

2. Optimized Infection and Genetic Engineering

To achieve efficient and precise genome editing, Ubigene leverages a low multiplicity of infection (MOI) strategy during lentiviral transduction, ensuring that each cell receives a single gRNA construct. This "one virus, one gRNA per cell" approach is critical for interpreting screening data accurately, as it reduces confounding effects from multiple simultaneous edits in a single cell.

3. Exceptional Reproducibility

Standardized manufacturing and rigorous batch-to-batch validation allow researchers to replicate experiments with confidence. By minimizing technical variability, Ubigene CRISPR Library Cell Pools provide a robust foundation for comparative studies, whether across different experimental conditions, cell types, or laboratories.

Ubigene CRISPR Library Cell Pools are versatile tools for a wide range of applications in basic and applied research:

1. Genome-Wide Loss-of-Function Screens: Identify essential genes required for cell viability, proliferation, or differentiation.

2. Targeted Gene Discovery: Focus on specific pathways or gene families to understand their role under physiological or stress conditions.

3. Drug Response Studies: Screen for genes that modulate sensitivity or resistance to small molecules, biologics, or environmental stressors.

4. Mechanistic Studies: Dissect signaling pathways, metabolic networks, or gene regulatory circuits in complex cellular contexts.

By combining Cas9-mediated gene editing with a high-coverage gRNA library, researchers can systematically perturb gene function at scale, providing deep insights into cellular processes and disease mechanisms.

Ubigene's CRISPR Library Cell Pools offer a turnkey solution for functional genomics studies, reducing the time, labor, and technical complexity associated with generating and validating custom knockout libraries. They provide:

• Immediate readiness for high-throughput screens

• Reliable and reproducible gene coverage
