Formalin Fixed Sample Collection is Strictly Confidential!

Blood or tissue samples are generally required for gene hunting projects. Some projects require that disease diagnosis is confirmed. These projects will include heart disease, PKD and amyloidosis. Formalin fixed tissues may be required to confirm the pathology. Formalin fixed tissues are extremely difficult for DNA isolation and destroys the DNA into small pieces. Please do not put the samples for DNA analysis in formalin.

Tumors should be sent immediately, but on ice, NOT frozen or formalin fixed! Extremely important, please plan ahead if possible! We will attempt to grow the cells from the tumor, freezing will kill the cells. Insulate the tumor from the ice packs to prevent freezing. Wrap the tumor in paper towels that are saturated with saline then place in a baggie. We will section the tumor for formalin fixation for pathology upon arrival.

Instructions for sending formalin fixed samples:

Samples do not need to be sent by overnight courier and should be fixed for at least several days prior to shipment.

Tissues should be sectioned for complete penetration of the formalin into the tissue. Please contact the lab if you are unfamiliar with proper sectioning for pathology. Please send an e-mail to the lab The Lyons Den or call: (530) 752-7127.

You must package the sample as described below, thus be prepared with the packaging.

Notify the lab that the sample is being shipped. Please send an e-mail to the lab The Lyons Den or call: (530) 752-7127. Please provide your contact information, especially your own phone and or e-mail address, so that we can notify you of the sample's arrival.

Please include details on the sample, such as a pedigree and project information. Many samples come to the lab and may be processed by various individuals.

Packaging Instructions:

Remove the tissue from the formalin. Large amounts of formalin should not be sent in the mail.

Place the tissue in a zip lock baggie with paper towels . Label the baggie with the type of tissue.

Place the sample in a small box.

The sample can be sent by regular mail and at room temperature.

Seal the sample in the box.

Blood and tissue samples for DNA should be packaged separately. Review the packaging information for blood samples and for tissue samples.

Re-imbursement for tissue sample collection:

Many projects have special funding thus the cost for the collection of samples for these projects can be re-imbursed. Re-imbursement can be made directly to the owner or the veterinary clinic. The owner will have to provide a proper mailing address, phine number and social security number to be established as a vendor by the university. Re-imbursement should take only a week or so. Re-imbursement can also be made directly to the veterniary clinic if they will accept a payment after the procedure. Invoices should be sent with the samples or by a separate mailing.

All samples are for research purposes only. Any donations of sampling costs and shipment expenses is greatly appreciated!
