We recommend to send samples in screw cap (with gasket) Eppendorf tubes packed in such a way that are cushioned from the effects of FedEx.  If a gasket-equipped tube is not available, use Parafilm to assure that the cap does not pop off in shipping.  Keeping the sample cool is at the discretion of the investigator.  It is not necessary to preserve biological activity or structural integrity of the sample unless solubility will become an issue.  Dried samples and samples on PVDF do not require being kept cool.  Before sending a sample, many of our clients alert us by e-mail that it is coming so we can look for its arrival.

The Amino Acid Analysis Sample Submittal Form should accompany the sample.  This form is available on this website and can be filled out on line.  It cannot be sent electronically except as an attachment and we prefer that it is printed out and accompanies the sample.
