CRISPR Basic Services    

We are currently undergoing a biotechnology revolution. Genomics advances led by CRISPR/Cas9 technology have greatly accelerated genomic engineering research. As CRISPR opens the door to more and more applications every day, more and more researchers are using this technology for research.

How does the CRISPR/Cas9 system work?

The CRISPR/Cas9 system relies on two main components: guide RNA (gRNA) and CRISPR-related (Cas) nucleases.

  • gRNA is a specific RNA sequence that recognizes a target region of a target DNA and directs the Cas nuclease to edit there.

    gRNA consists of two parts:

    ➢ CRISPR RNA (crRNA) - A 17-20 nt sequence complementary to the target DNA, a customizable component that achieves specificity in each CRISPR.

    ➢ Trans-activating crRNA (tracrRNA) - Serving as a binding scaffold for Cas nuclease.

    ➢ sgRNA (single guide RNA) - As the name suggests, sgRNA is a single RNA molecule that contains a custom-designed short crRNA sequence and a scaffold tracrRNA sequence. sgRNA can be artificially synthesized or prepared from DNA templates in vitro or in vivo.

  • CRISPR-related protein is a non-specific endonuclease. It is directed by gRNA to a specific DNA locus and forms a double-strand break in it. There are several versions of Cas9 nuclease isolated from different bacteria. The most commonly used is Cas9 nuclease from Streptococcus pyogenes.

What do we offer?
