Custom dCas9-KRAB Overexpressing Cell Line Development Service

The dCas9-KRAB overexpressing cell line is a versatile tool for CRISPR interference (CRISPRi), enabling targeted and reversible gene silencing without altering the genome. By fusing a nuclease-inactive Cas9 (dCas9) with the KRAB repression domain, this system uses sgRNAs to guide the complex to specific promoters, effectively suppressing transcription through epigenetic mechanisms. This approach is ideal for studying gene function, regulatory elements, non-coding RNAs, and for conducting loss-of-function screens in areas like drug discovery and disease modeling. Creative Biolabs offers custom dCas9-KRAB cell line development, delivering stable, validated monoclonal lines with high expression levels. Our cell lines are compatible with both commercial and custom CRISPRi libraries, supporting flexible, scalable research across various applications.

Introduction of Custom dCas9-KRAB Overexpressing Cell Line Development Service

The dCas9-KRAB overexpressing cell line is a powerful genetic tool for transcriptional repression in CRISPR interference (CRISPRi) systems. It employs a nuclease-inactive Cas9 (dCas9) fused with the KRAB domain, a strong transcriptional repressor. Guided by sequence-specific sgRNAs, the dCas9-KRAB complex binds to gene promoters or regulatory regions and recruits chromatin-modifying factors to epigenetically silence gene expression—without introducing DNA breaks or altering the genome. Establishing a stable dCas9-KRAB overexpressing cell line allows precise, reversible, and long-term gene silencing, ideal for loss-of-function studies, functional genomics, epigenetics, and disease modeling, especially when permanent gene knockout is impractical or introduces unwanted effects.
