Background on 08 distribution

Quality Control Process

This year the Registry has undertaken extensive quality control measures in order to better ensure the accuracy of DNA parts sent to the iGEM 2008 teams. This QC process began in February and has examined each part currently in the Registry to determine if the plasmid and the part within are correct according to the documentation provided with each submission. The results for each part were then posted on the Registry's DNA repository page [ ], allowing iGEM teams to access this information before using the submissions to create their own parts.

Grouping of parts for QC project

Each part in the Registry was assigned a well in a specific 96 well staging plate according to its antibiotic resistance and its base pair length. This grouping made it easier to examine the parts against their known antibiotic resistance and to then sequence their DNA.

Streaking for Single Colonies

Once it was decided which part would be assigned to each plate, bacterial stocks containing parts were plated and streaked for single colonies.

Parts in the Registry prior to iGEM 2007 were kept in glycerol stocks in the Registry's -80C freezer, where they were directly streaked onto Petri dishes with appropriate antibiotic and grown overnight at 37C.

The rest of the parts - ones submitted by iGEM 2007 teams - were received as DNA and transformed into competent cells. Once transformed, they were also plated onto Petri dishes with appropriate antibiotic and allowed to incubate overnight at 37C.
