The DNA Detective

A crime scene investigation kit, in which the students get to investigate which of the suspects committed the crime by using DNA analysis. This kit allows students to undertake gel electrophoresis without digesting the DNA first. The kit is designed for 16 groups and provides enough pre-digested DNA for each group to run 6 samples on a gel; giving them all plenty of opportunity to develop the practical skills needed for electrophoresis.


This kit allows students to practice the skills needed for DNA electrophoresis, which is an important technical requirement on most A-level courses. Students will solve the crime using gel electrophoresis to analyse DNA samples; matching DNA from a blood sample found at the crime scene with that of a suspect.

Our wipe-clean quick-glance student guide makes the practical easy to follow and allows students to learn the skills needed for this useful technique.

Our more comprehensive teacher/technician guide aids in setting up and teaching the practical.

The kit works with our NCBE gel electrophoresis base unit.


The module contains materials for two complete ‘runs’ of the DNA Detective practical, each with eight students or working groups.

  • DNA ladder sheet
  • 8 student guides
  • 1 teacher/technician guide
