Forensic DNA fingerprinting has become a universally accepted crime-fighting tool. Recent advances use the polymerase chain reaction (PCR) to amplify human DNA obtained from crime scenes. This experiment, based on a crime scene scenario, has an inquiry-based component. Kit includes: instructions and Ready-to-Load dye samples for 12 gels. All you need: electrophoresis apparatus, power supply, automatic micropipet and tips, balance, microwave or hot plate, visualization system. EDVO-Kit 130-B contains pre-digested DNA samples ready for electrophoresis sufficient for twelve (12) agarose gels with the use of InstaStain Methylene Blue. Reagent quantities are based upon the use of Horizontal gel electrophoresis apparatus, Model M12 and sample volumes aliquoted at 40 �l each. A: DNA Standard marker, B: Crime scene PCR reaction, C: Suspect 1 PCR reaction, D: Suspect 2 PCR reaction, E: Suspect 3 PCR reaction, Practice Gel Loading Solution, 100 ml plastic graduated cylinder (packaging).
