CRISPR Modulation

CRISPRiCRISPRadCas9 stable cell linesControls

Modified CRISPR-Cas9 systems for activation or repression of endogenous gene transcription

Adding new dimensions to the CRISPR toolbox, the CRISPRmod family of gene modulation tools promote (CRISPRa) or repress (CRISPRi) target gene transcription, without cutting the DNA.
Benefits & applications

  • Endogenous modulation – control expression within a gene's native context
  • CRISPR level specificity – leverage PAM-anchored targeting
  • Multiplexing – simultaneously activate or inhibit multiple genes
  • Orthogonal validation – use in parallel with CRISPR knockout or RNAi for robust datasets

Gene Editing

Understand disease mechanisms at the genomic level. 

Gene editing refers to the process of changing regions of cellular DNA. The most common gene editing techniques involve inactivating a gene's function (knockout), introducing or correcting a SNP mutation, or adding a reporter tag to an endogenous gene (knock-in). These changes are permanent and heritable, resulting in a newly engineered cell line. With Horizon Edit-R™ CRISPR-Cas9 reagents, researchers can make targeted, specific edits to any gene in practically any cell type. Additionally, Horizon offers a wide selection of pre-made edited cell lines and expert genome engineering services.

Gene Knockdown

IncRNA | Custom siRNA design | Cherry-pick library tool | RNAi libraries

siRNA - Proven synthetic siRNA solutions for straightforward loss-of-function studies.

shRNA - Lentiviral vector-based reagents for transient, long-term, inducible, and in vivo  RNA interference.

microRNA (miRNA) - Rationally designed miRNA modulation reagents to up-regulate or suppress endogenous mature miRNA function.

RNAi Controls - enable accurate interpretation for reliable, reproducible results.

CRISPRi - Transcriptional repression of endogenous gene expression

RNA interference (RNAi) remains the most simple yet effective method for target gene knockdown in loss-of-function experiments. Dharmacon has pioneered the development of novel siRNA, shRNA or microRNA technology for over 20 years, offering a broad portfolio of trusted synthetic and expressed reagents for highly specific and efficient gene silencing.
