Cloning Troubleshooting

Welcome to the troubleshooting hub! Below are some helpful tips and troubleshooting strategies for common cloning problems in E. coli.

Cloning is difficult. No one who has ever picked up a pipette in the lab would debate this fact. However, cloning shouldn't be impossible! This page exists to help students and teams who are struggling with cloning and other molecular techniques. Treat this page as another resource in your troubleshooting endeavors rather than the be-all, end-all resource for iGEM cloning problems. I hope this will be a helpful resource for every iGEM team!

iGEM Protocols

Below are the links to the various protocols that iGEM Headquarters has provided over the years. These protocols can also be found through the Parts Registry page under the "Help" and "Protocols" links in the black toolbar at the top of the page. These are another useful resource that teams should read through when they're experiencing cloning problems.
