Shipping your DNA Purification Samples

Bacteria can be delivered at room temperature when streaked on an agar plate (please make sure you see colonies before you send the plate, and the streaking plate is from one colony). Glycerol stocks need to be transported in dry ice and kept frozen. Starting DNA sample can be delivered at room temperature. Bacterial culture can be delivered at room temperature (for local customers only). 

Free Local Sample Pickup

Local customers (San Francisco Bay Area)

We will pick up your sample for DNA purification and deliver final DNA to you free of charge.

Domestic customers

You may ship bacteria on a plate (O.K. for room temperature) via FedEx. If you are shipping glycerol stock, it needs to be shipped in dry ice and kept frozen. DNA can be shipped at room temperature via FedEx

International customers

We only recommend shipping DNA because shipping delays may occur, which could cause sample damage.
