DNA Sampling Tips

1. Wash your hands.

2. Clean the area by removing all loose hair and foreign matter.

3. Pull (DO NOT CUT) 40 or more hair strands. Grasp a small group of hair close to skin and yank in one swift motion (pliers can be used). A good place to collect hair is the base (root) of the tail.

4. Examine the ends of the hair strands for the presence of root bulbs. Hair roots are necessary for DNA testing. If the majority of the hair strands lack root bulbs, discard sample and try again. Do not send hair without visible root bulbs. DO NOT TOUCH root bulbs.

5. Hair samples must be placed in a paper envelope labeled with the animal’s name, owner name and date of sample. DO NOT place sample in a plastic (zip-lock) bag, the sample must be able to breath. Do not trim the hair; keep full length. Keep root bulbs aligned (together). You may tape the sample to an index card if you are careful to not touch the root bulbs or tape them. Do not touch the root ends of the hair sample; you will contaminate it with your own DNA. Seal envelopes WITHOUT licking adhesive (i.e. use tape or self-adhesive envelopes.)

6. Repeat for each additional animal being sampled. When sampling several animals in the same session, be very careful that your hands are clean and there is no hair or contamination from the previous sample.

7. You're done. You can send sample envelopes to IYAK.
