DNA PATERNITY TESTING || By using DNA fingerprinting, or DNA profiling, a child's paternal relationship can be tested by comparing the child's DNA profile to the profile of the mother and possible father to determine if an individual is the father or not.
DNA KIT || The kit contains enough materials for 8 groups of students. In this activity students will use electrophoresis to separate DNA samples of a child, mother, and two potential fathers to determine if either father is a possible paternal match.
GREAT FOR ELECTROPHORESIS EXPERIMENTS || This kit is excellent for lab and classroom use. Teachers Guide and Student Study Guide copymasters included.
INSTRUCTIONS || Product instructions and safe usage & storage information is printed directly on the product bottle. SDS is available upon request. For Laboratory Use Only. Not for drug, food or household use. Keep out of reach of children.
