Model CRISPR Biology and CRISPR-Cas9 Biotechnology!

NEW CRISPR Adaptive Immunity Kit©

Discover how bacteria remember past viral infections and activate their CRISPR systems to search for and destroy the remembered virus’ DNA - preventing infection. This introduction to CRISPR biology will prepare your students to  understand how the Cas9 protein works. 


NEW Making the Cut with CRISPR-Cas9©

Model how the Cas9 protein is programmed with RNA to search for and identify specific sequences of DNA before making the double-stranded cut. Explore and discuss how Cas9 is being engineered with new features that make it a useful tool for editing the human genome.


With the CRISPR Adaptive Immunity Kit's engaging foam pieces, your students can:

  • Build the bacteria’s CRISPR array which includes Cas9, tracr, spacer and repeats.
  • Detect the presence of viral double-stranded DNA.
  • Integrate a short fragment of this viral genome into the bacteria’s CRISPR array.
  • Express the CRISPR array to create the Cas9 proteins and the guide RNA.

With Making the Cut with CRISPR-Cas9's colorful foam pieces and placemat your students can:

  • Build a schematic model of the CRISPR-Cas9 RNA-guided endonuclease, including the viral double-stranded DNA and dual guide RNA.
  • Understand how the Cas9 protein binds to a specific sequence of viral double-stranded DNA at a PAM site - and cuts it.
  • Demonstrate how that cut destroys viral genome and prevents the infection of bacteria.
  • And much more!
