Welcome to the PSI Material Repository

The PSI-MR stores, maintains and distributes protein expression plasmids and vectors created by the PSI centers. We currently have ~16,000 PSI plasmids and empty vectors available for request with an additional PSI plasmids added monthly.

The PSI-MR has moved to ASU!

We are now distributing PSI plasmids from the DNASU Repository! Please see here for more information about how to order plasmids.

New PSI-MR Features

DNASU Plasmid Repository

Our repository has more than just PSI plasmids! We have a collection of over 100,000 plasmids in over 439 organisms in 291 vector backbones. This collection includes:

1. Breast Cancer 1000 (BC1000): A collection of clones containing 1000 human genes related to breast cancer  
2. Yeast - All of the open reading frames (ORFs) of S. cerevisiae in the Gateway Entry vectors
3. >5,500 S. cerevisiae  ORFs in two yeast expression vectors pBY011 and ZM552
4. A collection of the 5,600 genes encoded by P. aeruginosa
5. Complete genome collections for Bacillus anthracis, Francisella  tularensis, Vibrio cholorae and Yersinia pestis 
6. A set of >500 human kinases both in the Creator Entry Vector and two mammalian retroviral vectors (pJP1520 and pJP1563)
7. A set of 7,000 clones of human genes in the Gateway Entry vector

You can view an overview of these collection here or see the details of these collections here and also search for and request these plasmids through our website.
