CRISPR interference (CRISPRi) is a genetic perturbation technique that allows for sequence-specific repression of gene expression in prokaryotic and eukaryotic cells. [1] It was first developed by Stanley Qi and colleagues in the laboratories of Wendell Lim , Adam Arkin, Jonathan Weissman , and Jennifer Doudna . [ 2 ]
Apart from knock-out there are also knock-down (CRISPRi) and activation (CRISPRa) libraries, which use the ability of proteolytically deactivated Cas9-fusion proteins (dCas9) to bind target DNA, which means that a gene of interest is not cut but is over-expressed or repressed. It made CRISPR/Cas9 system even more interesting in gene editing.
CRISPR interference (CRISPRi) on the other hand utilizes a catalytically inactive nuclease to physically block RNA polymerase, effectively preventing or halting transcription. [8] Perturb-seq has been utilized with both the knockout and CRISPRi approaches in the Dixit et al. paper [2] and the Adamson et al. paper, [1] respectively.
CRISPR activation (CRISPRa) is a gene regulation technique that utilizes an engineered form of the CRISPR-Cas9 system to enhance the expression of specific genes without altering the underlying DNA sequence.

The exact protocol for lentiviral production will vary depending on the research aim and applied library. [35] [43] [44] If a two vector-system is used, for example, cells are sequentially transduced with Cas9 and sgRNA in a two-step procedure. [35] [44] Although more complex, this has the advantage of a higher titre for the sgRNA library virus ...
