This is the last call for submitting Fly-TILL orders. For reasons having to do with both resources and demand, we are going to stop the Tilling Service in April 2011. In order to meet this deadline, all TILLING orders must be placed on or before January 31, 2011. To learn more about Fly-TILL or to put orders in the queue, go tohttp://tilling.fhcrc.org/fly/. The Web site describes how TILLING works, what Fly-TILL expects to deliver, answers to frequently asked questions and user policies.
