Step 2 (Optional): Download the Guidelines for International Shipments

Shipping from outside of the US? Download and follow these Guidelines.

Step 3: Prepare your samples for Shipment

  • Extract RNA using a trusted protocol/kit including DNase treatment, or discuss extraction options with your Project Scientist. 
  • Check to make sure your samples meet our quantity/quality requirements.
  • If shipping extracted RNA, the sample must be in nuclease-free water and shipped frozen on dry ice.
  • If shipping FFPE, we recommend shipping with a cold pack.
  • If shipping frozen tissue or cell pellets, please ship frozen on dry ice.
  • Include a copy of your quote and sample list spreadsheet when you mail samples.

Concerned about extractions? Contact your Project Scientist to add RNA extraction to your project quotation.

Step 4: Download the Sample List Spreadsheet

Please download the appropriate Sample List Spreadsheet  and fill in your sample info.


Sample List Spreadsheet


Ensure the sample names on your spreadsheet match the labels on your tubes. If the samples names do not fit on the tube labels, please use simplified names and include a legend to match the shortened/simplified name to the longer name.
