Exploring Electrophoresis and Forensics Demonstration Kit

(in stock)


Beginning—Easy to perform, requires little or no prior knowledge.

  • Introduces advanced concepts of PCR and DNA fingerprinting
  • Gels can be run in 45 minutes with five 9-V batteries or overnight with 1 battery
  • Introduces forensic techniques

This technically simple experiment simulates the use of DNA in forensic investigations. Students cast agarose gels, load predigested DNA, and perform electrophoresis. They use the banding patterns of the DNA in the gel to compare the DNA fingerprints of 2 suspects with evidence and victim DNA. Demonstration Kit includes enough materials for 2 demonstrations, plus free 1-year access to digital resources that support 3-dimensional instruction for NGSS. Note: Order bulk DNA 2 weeks prior to desired ship date.
