Who are we?Harvard Institute of Proteomics
• High-throughput methods for biomarker, antigen and interaction discovery; cell-based screens; other functional assays
• Clone production—ORF cloning for human genes and several microorganisms
• Plasmid repository established 2004– Currently >80,000 clones
• Plasmid information curated by a PhD level scientist prior to import
• Plasmid Information Database (PlasmID)• Requests daily, distribute world-wide

How does it work?Receiving Plasmids
Working sample
1 or more on-site archival sample
Arrive as DNA
Transformation & Robotic Colony Pick
Liquid Culture
• Phage-resistant cells• Sequence Verified • Barcode labels• Automation

How does it work?Storing Plasmids
(Thermo, Zmation)
BioBank Features• Two -80 freezers • Total sample capacity of 160,000• Samples stored in 2D barcode-labeled tubes• BioBank Software integrated with PlasmID

Overall Goals of the PSI-MR
• Centralized storage & distribution of information and samples for the >100,000 plasmids created at PSI sites
• Quality analysis and control at every step– Barcode labels and Information Tracking at All Steps– Single Colony Selection & Use of Phage-Resistant Bacterial Host
Strains– End read Sequencing & Analysis – State-of-the-Art Freezer Storage System (BioBank)
• Scientifically Curated plasmid Information in Oracle Database (PlasmID)– Saves searchable information about all plasmids– Linked to PSI Knowledgebase– Ordering directly from website
• Develop terms under which plasmids can be distributed under minimally restrictive terms– Depositors Agreement and Expedited Process MTA
![Page 9: PSI Materials Repository: Goals and Progress Josh LaBaer Director, Harvard Institute of Proteomics Harvard Medical School.](https://reader033.fdocuments.in/reader033/viewer/2022051516/56649db65503460f94aa8364/html5/thumbnails/9.jpg)
Early Goals
• Create points of contact• Collect & curate info on vectors• Establish Depositor Agreements• Establish clone submission format• Transfer of information to PSI-MR• Update PlasmID to reflect connection
to PSI• Transfer of samples to PSI-MR• Create PSI-MR website
![Page 10: PSI Materials Repository: Goals and Progress Josh LaBaer Director, Harvard Institute of Proteomics Harvard Medical School.](https://reader033.fdocuments.in/reader033/viewer/2022051516/56649db65503460f94aa8364/html5/thumbnails/10.jpg)
Current Goals
Create points of contactCollect & curate info on vectorsEstablish Depositor Agreements• Establish clone submission format• Transfer of information to PSI-MR• Transfer of samples to PSI-MR• Update PlasmID to reflect connection
to PSI• Create PSI-MR website
![Page 11: PSI Materials Repository: Goals and Progress Josh LaBaer Director, Harvard Institute of Proteomics Harvard Medical School.](https://reader033.fdocuments.in/reader033/viewer/2022051516/56649db65503460f94aa8364/html5/thumbnails/11.jpg)
Depositors Agreement• Agreement that sets the terms for distributing
plasmids deposited by the PSI-MR sites• Why do we need a DA?
– Gives the Materials Repository permission to distribute the property of others
• Expressly prohibited by MTAs
– Appropriately assigns responsibility for the safety of distribution
• MTAs do not address these issues
– Universal set of operating conditions– Establishes the MTA that will accompany the
clones
