- American Type Culture Collection (ATCC) maintains yeast stocks and clones.
- EUROSCARF, the EUROpean Saccharomyces Cerevisiae ARchive for Functional analysis, maintains a collection of systematic deletion strains searchable by gene name.
- National Collection of Yeast Cultures (NCYC) maintains over 3,100 non-pathogenic yeasts, including type strains, strains of general interest for education and research, strains of industrial importance, and genetically marked strains.
- Common Access to Biological Resources and Information (CABRI) includes catalogs from European culture collections for yeast and other organisms.
- Addgene is a non-profit plasmid repository that distributes many plasmids for yeast research. In particular, Addgene is distributing a collection of Yeast Advanced Gateway Destination Vectors created by Dr. Susan Lindquist's laboratory.
