What is CRISPR libraries?

CRISPR technology provides a powerful tool for genetic manipulation and functional genomics research.

CRISPR libraries refer to a set of gRNA libraries that are designed and constructed to screen and identify genes that affect a particular phenotype or disease process. CRISPR libraries contain a large number of guide RNA sequences, each of which is specifically designed to target a different gene. By transfecting the gRNA library into cells and screening for desired phenotypes, researchers can identify candidate genes that may be involved in the regulation of the phenotype or disease process. CRISPR libraries have been widely used in basic research, drug discovery, and disease treatment.

Compared with traditional cDNA and RNAi libraries, CRISPR libraries have a number of advantages, including higher targeting efficiency, lower noise, and more targeted knockout. Here are some suggestions on how to effectively utilize CRISPR libraries to speed up your research:
1. Target gene selection: You can use published literature, pathway databases, and other resources to identify candidate genes that are related to your research topic.
2. Design gRNA: Designing guide RNA is the key step in CRISPR technology. Guide RNA should be specifically targeted to the gene you want to knock out. There are many online tools available to help you design gRNA with high targeting efficiency and low off-target rate.
3. Screening process: Once you have designed the gRNA, you can start the screening process. The most commonly used screening method is pooled screening, which involves transfecting the guide RNA library into the target cell line and selecting the positive clones after several rounds of screening.
4. Data analysis: After the screening process, you will obtain a list of candidate genes that affect your research topic. You need to further analyze these genes to identify the key regulators. You can use bioinformatics tools and pathway databases to help you annotate and prioritize candidate genes.
5. Validate the candidate genes: Finally, you need to validate the candidate genes identified by the screening process. This can be done by individual validation experiments or by performing rescue experiments to confirm the gene's function in your research topic.
In this way, CRISPR libraries provide an efficient way to identify candidate genes that affect a particular phenotype or disease process. By following the steps, you can effectively utilize CRISPR libraries to speed up your research and gain insights into the genetic basis of your research topic.

[Research Frontier] New Trends in Prime Editing: Point Mutated Cells for Preclinical Gene Therapy

Image
  Prime editing is an improved gene editing technology based on the CRISPR/Cas system to achieve precise fragment insertion, deletion, and arbitrary substitution of bases at the target site of the genome, with higher accuracy and lower error rate. When it came out, it attracted widespread attention from many scientific researchers, and extensive research was conducted on the treatment of hereditary diseases, gene mutation diseases, and cancers. For example, correcting the mutant genes to treat genetic diseases or editing oncogenes in cancer cell genomes to prevent them from growing and spreading. The following three articles are about the clinical treatment of Prime Editing, bringing you the latest research trends.   Prime editing helps in the treatment of β - thalassemia, and no off-target  effect was detected         β - thalassemia is a hematopoietic system disease caused by a single gene mutation in the hemoglobin (HGB) subunit beta gene (HBB), res...

Prime editing 101：what is prime editing? | EDITGENE

Image
Prime editing is an   advanced   gene editing technology proposed by David R. Liu's team in 2019. It can mediate targeted insertions, deletions, and twelve base substitutions without DSBs and donor DNA templates to achieve precise gene editing. Prime editing has developed rapidly in the past 4   years and has shown great potential in various fields.   Prime Editing  mechanism The prime editing system consists of Prime editing guide RNA (pegRNA) and nCas9. PegRNA can be divided into a guide RNA at the 5' end, a Cas9 binding region in the middle, and a PBS (Prime-binding site) at the 3' end; nCas9 is a Cas9 nickase with single-stranded cleavage activity and fused with M-MLV reverse transcriptase. The complex recognizes PAM under the g uidance of pegRNA   and binds to the target DNA strand complementary to the guide RNA. Cas9 enzyme cuts the 3rd and 4th nucleotides of the original spacer sequence upstream of PAM to generate a nick; the broken DNA single strand...
