The Repository is accepting and storing three tyes of samples:
- Cheek Swab DNA
- Blood DNA
- Frozen Tumor Tissue
These are listed above in increasing order of value to researchers with tumor tissue being the highest value. Each of them require different instructions on how to collect and ship to the Repository at Michigan State University (MSU). It is very important that the specific instructions be followed for each type of submission which will be detailed below.
Note that we want cheek swab and blood DNA from healthy dogs as well as dogs that may be ill. Tumor tissue is obviously only from affected dogs.
General Submission Information
You will need the proper collection and shipping materials to get the sample(s) to MSU. Marlee Richter at MSU can ship you a collection kit at a very nominal cost. Click here for more information. Note that your Vet may already have the necessary supplies and that is fine too as long as the collection procedures and shipping instructions are followed. Note that Marlee's contact information is at the upper right and includes her phone and fax numbers.
You will also need to fill out and sign a repository submission form for each dog. These need to be sent in to MSU along with the sample(s). See the item in the sidebar to the right.
Some detailed information on collecting each type of sample is provided below. You can also go to the submission instructions page of the MSU web site for a chart that will walk you through the various types of submissions.
Tumor Tissue Submission
This is without a doubt the most difficult submission as it happens during a period of extreme grief. Your veterinarian must remove a section of the tumor tissue from your dog shortly after death. Note that if the tumor has not already had a specific pathologigical diagnosis, you will need two tumor samples removed. The sample that is being submitted to the Repository needs to be frozen. This can be a freezer at your vet's or even your own home freezer. You can then take days (or weeks) to get the proper shipping materials and send the tumor to MSU. Please refer to these tumor submission instructions for more information regarding the collection and shipping of a frozen tumor.
If there has not been a specific pathological diagnosis of the exact type of tumor, the second sample will need to be collected as formalin fixed tissue and submitted to a lab for diagnosis. Your vet should be familiar with this procedure. Please refer to these tumor diagnosis instructions on the MSU web site for more information regarding getting a confirmed diagnosis.
One of the confusing issues with tumor submission is that specific diagnosis of the tumor type and submitting a sample to the repository are two different submissions. If your vet has already had a pathological diagnosis done on the tumor, you do not need to do this again. Simply submit a copy of the diagnosis report with your submission to the Repository. Please contact Marlee for more information or clarification.
Blood DNA Submission
Blood DNA collection needs to be done in the proper type of tube and kept chilled but not frozen. Please refer to these blood DNA submission instructions for more information regarding submitting a blood DNA sample.
Cheek Swab DNA Submission
The important thing to remember about cheek swab submissions is that to prevent DNA contamination, the dog must not have anything to eat for two hours before the DNA is collected. Water is ok at any time. Please refer to these cheek swab DNA submission instructions for more information regarding submitting a cheek swab DNA sample.
