Plasmids can be submitted in either form. For DNA, aliquot 15 µL of DNA into a 1.5 mL microfuge tube (at a concentration of 0.1 -1µg/µL) and use Addgene's prepaid shipping materials.
For bacterial cultures, streak the glycerol stock onto a plate with the appropriate antibiotic (please streak only 1 sample per plate). After streaking, seal each plate with parafilm. Please wrap the plates in bubble wrap or similar padding, and then use Addgene's prepaid shipping materials to return them to our facility.
Please note that if you have more than 5 bacterial plates, we do not recommend using Addgene's deposit kit. Rather, you will be responsible for selecting an appropriate package and shipping the samples back to Addgene according to safety guidelines.
