Overview Service Process Examples and Solutions Applications Frequently Asked Questions

Overview

CRISPR screening for drug development involves the use of CRISPR/Cas9 technology to perform genome-wide or targeted genetic screens in various cellular models. This approach allows researchers to identify genes that are essential for disease progression, drug resistance, or therapeutic responses. The ability to manipulate gene function with high precision and scalability makes CRISPR screening an invaluable tool for discovering new drug targets and understanding the genetic basis of disease.

Service Process

The process of CRISPR screening for drug development involves several critical and interrelated steps:

Library Design and Construction: Designing and constructing a CRISPR library tailored to the specific needs of the study. This may include genome-wide libraries or custom libraries targeting specific gene sets.
Cell Line Preparation: Selecting and preparing appropriate cell lines for screening. This includes ensuring that the cells are amenable to CRISPR/Cas9 editing and relevant to the disease or pathway of interest.
CRISPR Delivery: Introducing the CRISPR library into the target cells using methods such as lentiviral transduction, electroporation, or other efficient delivery systems.
Screening and Selection: Treating the edited cells with drug candidates or other conditions of interest and selecting for desired phenotypes, such as cell survival, proliferation, or apoptosis.
Data Analysis: Performing high-throughput sequencing and bioinformatics analysis to identify the genes affected by the CRISPR edits and their impact on drug response or resistance.
Validation: Validating the identified targets through secondary screens and functional assays to confirm their roles in the disease or drug response.
