Are you looking for a simple means to boost the efficiency of gene editing and also to reduce the off-target? Yes, it does exist – in one word: 4-hydroxy Tamoxifen. That’s the HIT-CAS9.

Hybrid drug inducible CRISPR/Cas9 technology, HIT-Cas9

Zhao et al revealed tight and effective drug control of the CRISPR Cas9 based on 4-Hydroxytamoxifen. doi: 10.1016/j.omtn.2018.08.022

They built a fusion between a mutated human estrogen receptor (ERT2) and the Cas9 endonucelase, which makes the CRISPR Cas9 dependent on 4-hydroxytamoxifen.

Single-cell isolation allows genomic and transcriptomic analysis of one individual cell. It is also required to build a monoclonal cell line from rare cell isolation, that could be for example CRISPR-CAS9 gene edited cells. There are 3 popular methods: serial dilution, micro-manipulation and flow cytometry. None of these are easy or simple, and they often require expertise and experience. Fortunately, a new solution for everybody has come! It’s designed to isolate a single cell in a few seconds, and it’s (quite appropriately) called the Smart Aliquotor.

CRISPR-CAS9 is a powerful technology for gene editing. It allows targeted modifications into the genome of the cell lines, IPSCs and ESCs. Despite the principle being pretty simple, in practice its use requires some expertise, and it can even turn into a time consuming adventure… That’s why the best way to benefit from it is most certainly through affordable services.

RNAi offer >70% knock-down of the gene expression, and thanks to CRISPR-CAS9 gene editing, it’s possible make a complete knock-out. The TUNR system offers the possibility to obtain intermediates with high, medium and low reduction of the gene expression and with the same quality of targeting as for knock-out. Let’s take a closer look at the TUNR technique.
