Sample Instructions – Tissues & Cadavers
ALL CONTRIBUTION ARE STRICTLY CONFIDENTIAL – ALL CATS CAN PARTICIPATE!
Blood or tissue samples are generally required for gene hunting projects. If a cat must be euthanized or has died, tissue samples or the entire cadaver can be collected for DNA isolation. If tissue samples can not be collected immediately by a veterinarian, the cadaver should be frozen. DNA degrades rapidly in tissues, thus samples should be sent frozen immediately was procured from the individual. Tissues samples that degrade less slowly include spleen and kidney and are the preferred tissues. The liver has many degrading enzymes and glycogen stores, thus liver is NOT a preferred tissue. Send any portions of the tissue that are not required for necropsy. 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. Formalin fixed tissues may be required for the pathology of specific projects (see Formalin fixed tissues). Tumors should be sent immediately, but on ice, NOT frozen! 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 a paper towels that are saturated with saline then place in a baggie.

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.
Place the tube/tissue/ cadaver in a zip lock baggie. Label with the type of tissue if appropriate.Place the sample in a small box with many frozen ice packs.The sample should stay frozen, thus be sure to include at least two ice packs.Seal the sample in the box.If also including a blood sample, insulate the sample with several paper towels and review the packaging information for blood samples. Send samples directly to the Lyons laboratory using this Submission Form

Reimbursement 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 veterinary 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!
