Our DNA fingerprinting kit is the perfect tool to introduce students to the world of electrophoresis and forensic science. DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if the two DNA profiles do not match, then the evidence cannot have come from the suspect.
Each kit contains DNA, agarose gel, electrophoresis buffer and DNA stain enough for 8 groups of students to cast and run the experiment and visualise the DNA separation. The gel takes approximately 5 minutes to load, 30 minutes to run and 15 minutes to stain, meaning the whole experiment can be completed in a one hour lesson, with convenient incubation periods for scientific discussion and teaching. Students will solve a crime using an unknown DNA sample from the crime scene and a series of suspects!
All you need is a horizontal electrophoresis system, power supply and pipettes all available from Cleaver Scientific.
