Improved method for transport of living cell cultures

An easy and cost-effective method for transport of living cell cultures whi ch avoids the use of dry ice and prevents bacterial contamination is descri bed. Cells are suspended in buffered culture medium in sealed and insulated 2 ml cryovials and are able to grow and survive in substantial numbers dur ing several days of storage and shipment at ambient temperature. Replating results in an identical repopulation in all cell lines. Not only tumor cell s but also fibroblasts seem to tolerate well this improved method for shipm ent.
