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 use Making the Cut with CRISPR-Cas9 and understand how the Cas9 protein works. 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.
