Site for collecting DNA

 

DNA Examinations

I sent this information to Gloria...which might also be helpful to the group on collecting oral samples.

Buccal (oral)

There are two sources of DNA used in forensic analyses. Nuclear DNA (nDNA) is typically analyzed in evidence containing blood, semen, saliva, body tissues, and hairs that have tissue at their root ends. Mitochondrial DNA (mtDNA) is typically analyzed in evidence containing naturally shed hairs, hair fragments, bones, and teeth.

Questions concerning nuclear DNA evidence should be directed to 703-632-8446. Questions concerning mitochondrial DNA evidence should be directed to 703-632-7572. Follow the Evidence Submission directions including Requesting Evidence Examinations and Packaging and Shipping Evidence.

   

Buccal (oral) swabs
  • Use clean cotton swabs to collect buccal (oral) samples. Rub the inside surfaces of the cheeks thoroughly.

  • Air-dry the swabs and place in clean paper or an envelope with sealed corners. Do not use plastic containers.
  • Identify each sample with the date, time, subject's name, location, collector's name, case number, and evidence number.
  • Buccal samples do not need to be refrigerated.

so sorry to hear about your brother. I don't know of ways to preserve
the DNA without one of the collection kits sent out with the test. I
might be wrong about this but I think there are more expensive tests
that can be done with hair. Another thing to consider is does your
brother have any male children because you can pick up your dad's side
via his male children and you can get your mom's mom's mom's etc side
via your own MtDNA.

again sorry to hear about your brother.
