Online Inquiry

CRISPR library construction services offer an innovative and comprehensive approach to high-throughput genetic screening and functional genomics. By creating a diverse library of CRISPR guide RNAs (sgRNAs), researchers can systematically target and modify genes across the genome, enabling the study of gene function, interaction networks, and disease mechanisms on a large scale. This service is essential for advancing our understanding of complex biological systems and for the development of novel therapeutic strategies.

Overview Service Process Examples and Solutions Applications Frequently Asked Questions


CRISPR library construction involves designing and synthesizing a large collection of sgRNAs that can target numerous genes or genetic elements simultaneously. These sgRNAs are then used in conjunction with the CRISPR/Cas9 system to induce targeted gene modifications across the genome. This high-throughput approach allows researchers to perform genome-wide screens, identify gene functions, and explore genetic interactions. The CRISPR library can be customized to target specific pathways, functional gene sets, or entire genomes, providing a versatile tool for a wide range of applications.

Service Process

The process of CRISPR library construction involves several critical and interrelated steps:

  1. Library Design: Designing the CRISPR library involves selecting target genes or genomic regions based on the research objective. This includes the design of sgRNAs to ensure efficient and specific targeting.
  2. sgRNA Synthesis: Synthesizing a large number of sgRNAs corresponding to the selected targets. This can be achieved through high-throughput oligonucleotide synthesis.
  3. Vector Construction: Cloning the synthesized sgRNAs into appropriate CRISPR vectors, which may include lentiviral, plasmid, or other delivery systems suitable for the experimental model.
  4. Library Amplification: Amplifying the CRISPR library to obtain sufficient quantities for downstream applications.
  5. Quality Control: Conducting quality control measures, such as sequencing, to ensure the integrity and representation of the sgRNAs in the library.
  6. Delivery and Screening: Introducing the CRISPR library into target cells using appropriate delivery methods, followed by screening and analysis to identify functional genetic changes.
