Product Details

Perform true CRISPR gene editing in your laboratory class!
CRISPR gene editing is revolutionizing scientific research. Now your students can do real CRISPR-Cas9 gene editing in the classroom using Bio-Rad's educational CRISPR gene editing kits.

  • Out of the Blue CRISPR Kit (FB2505) — apply CRISPR-Cas9 technology to disrupt the lacZ gene in E. coli and produce a phenotype that can be readily visualized through blue-white screening
  • Out of the Blue CRISPR Genotyping Extension (FB2504) — (optional) confirm the edit at the molecular level using PCR and agarose gel electrophoresis

The Out of the Blue CRISPR and Genotyping Extension Kits earned the 2020 Science Educators’ Best of Show award for “Best New Technology Innovation for Science”  from the National Science Teaching Association (NSTA).

Features and Benefits

  • Hands-on, true CRISPR gene editing — students get direct experience with this powerful technology
  • Visible phenotype — results can be observed with the naked eye in as little as 22 hr
  • Safe — familiar and common reagents and non-pathogenic, non-biofilm-forming bacteria generate a phenotype that is common to molecular biology
  • Accessible — does not require specialized equipment or techniques
  • Comprehensive, supportive curriculum — includes background about the components of a CRISPR-Cas9 system, the science — and math — behind its accuracy and flexibility, and the guided bioinformatic analysis of CRISPR targets students design themselves


Please note that, though some items may be shipped at ambient temperatures to reduce shipping costs, some items are to be stored refrigerated or frozen upon receipt to ensure longevity. 

Please store some components at 4°C or –20°C as indicated.


CRISPR-Cas9 genotyping extension kit, includes Out of the Blue Extension Refill Pack materials (12012708EDU), InstaGene matrix, and PCR, micro, and conical tubes. Requires Out of the Blue CRISPR Kit (12012608EDU) and electrophoresis reagents, sold separately. For educational use only.

With the Out of the Blue Genotyping Extension Kit, students use multiplex PCR and agarose gel electrophoresis to confirm the edit they made to the lacZ gene with the Out of the Blue CRISPR Kit (sold separately). A key step in CRISPR and gene editing research workflows, this genotyping activity offers students an opportunity to engage in the scientific process of compiling evidence from multiple sources to explain a phenomenon.


Each kit contains the following materials for 8 student workstations (2–4 students per workstation).
