Every plasmid sample enters Addgene the same way. A package is delivered by a mail courier and then the journey of transformation and storage begins. Some samples are submitted as bacterial colonies in petri dishes, but close to 80% of samples are received as DNA in a microcentrifuge tube. Once a sample enters Addgene’s lab, a series of events is triggered. Each step is tracked through barcoded tubes that are scanned into our Laboratory Information Management System (LIMS), a database we use to keep track of and manage all of the samples that come through our doors. It would be a nightmare if we didn’t have a simple way to track all of our 40,000 samples available for distribution!
