Water Quality Testing Iii: Multiplex Pcr Testing Of Water Contaminants. Drinking water is routinely tested for contamination. If screening tests positive, more sophisticated tests are required. One such test uses PCR in multiplex format. In this experiment, students will test for the presence of three separate, classroom-safe organisms in water sample using single PCR reaction. Kit includes: instructions, control DNA and primers, DNA ladder, proteinase K, PCR EdvoBeads, gel loading dye, agarose, electrophoresis buffer, InstaStain® Ethidium Bromide and FlashBlue™ stain.All you need: Automatic micropipets (5 50 µl) and tips, waterbath, ice, balance, microcentrifuge, thermal cycler, electrophoresis apparatus, power supply, microwave or hot plate, UV transilluminator. For: 25 Students
