PSI Materials Repository:Goals and Progress Josh LaBaer Director, Harvard Institute of Proteomics Harvard Medical School
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
Arrive as DNA Liquid Culture Transformation & Robotic Colony Pick How does it work?Receiving Plasmids Working sample 1 or more on-site archival sample • Phage-resistant cells • Sequence Verified • Barcode labels • Automation
How does it work?Storing Plasmids • BioBank Features • Two -80 freezers • Total sample capacity of 160,000 • Samples stored in 2D barcode-labeled tubes • BioBank Software integrated with PlasmID (Thermo, Zmation)

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
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
Current Goals • Create points of contact • Collect & curate info on vectors • Establish 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
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
Current Goals • Create points of contact • Collect & curate info on vectors • Establish Depositor Agreements • Continue to work with PSI institutions and PIs to get the Depositors Agreement Signed • 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

Send PSI site submission checklist and templates PSI-MR reviews data and communicates with PSI site about any changes PSI-MR contacts PSI site to send their samples PSI-MR receives samples, inputs data, and sequences samples. PSI-MR re-arrays samples, inputs data into PlasmID and makes clones available for purchase PSI-MR PSI-MR and PSI site work together to create computer compatible formatted files PSI-MR works with PSI site to acquire suitable samples PSI site compiles data and sends to PSI-MR for review PSI site reviews documents and emails PSI-MR with any questions PSI site prepares samples and sends to PSI-MR PSI Site ≤ 1 week 2-4 weeks ≤ 1 week 2-8 weeks 1 week Timeline 2 days 1-2 weeks Data Submission Sample Submission
Current Goals • Create points of contact • Collect & curate info on vectors • Establish Depositor Agreements • Continue to work with PSI institutions and PIs to get the Depositors Agreement Signed • Establish clone submission format • Send these documents to PSI sites • Transfer of information to PSI-MR • Transfer of samples to PSI-MR • Update PlasmID to reflect connection to PSI • Create PSI-MR website
