Submitting samples for genetic testing is a simple, straightforward process. Typically, tail biopsies of approximately 0.5 cm in length or ear clips/punches (preferred for rats) are submitted; however, other tissues including toe clips or internal organs, cell pellets, and purified DNA are also acceptable sample types. Samples may be collected and shipped in the format most convenient for you or your animal facility, including individual tubes or multi-well plates. We also offer 96-well sample collection kits, pre-packaged to include everything you need to send biopsies to us. To order the kits, please contact us at gts@crl.com.
Sample collection requirements and shipping directions vary depending on the specific sample type, collection format, and assay. Please contact us for specific instructions for your submission. All shipments should include a completed Sample Submission Form. If this is the first time you’re sending samples for a new strain, please be sure to contact us prior to submission to discuss protocol information and controls.
