My stab did not grow. What do I do?

Plasmid received within 30 days:

First, assess whether the plasmid was placed at 4°C upon arrival and that the plasmid was grown under the recommended growth conditions (e.g. used appropriate antibiotic), which can be found on the plasmid page. If both of these are true, please contact  


Plasmid received over 30 days ago:

Addgene requests any issues be reported within 30 days of receiving the plasmid as we cannot guarantee growth and plasmid integrity beyond that time window.
