The Yeast ORF library was designed for use in high-throughput chemical and genetic screens in Saccharomyces cerevisiae. This collection consists of over 4,900 yeast open reading frames (ORFs) that have been adapted with Gateway recombination sites and subsequently cloned into a yeast expression vector. It is available as a library of plasmids transformed into E. coli or of yeast strains expressing the corresponding ORF as a C-terminal fusion protein under control of a regulatable GAL promoter.
ORFs in this collection can be expressed directly in their expression vector or transferred to other Gateway-adapted vectors. The ORF expression vector plasmid, pGB1805, encodes a C-terminal fusion tag that includes 6xHIS, single HA epitope, 3C protease cleavage site, and the IgG-binding domain from Protein A.
ORF strains provide a shortcut to expressing yeast proteins with no PCR or cloning required
The optional E. coli format enables Gateway-adapted cloning to alternative yeast strains and plasmids
All yeast-format constructs have been verified by western blotting to express protein of the correct length
The versatile 19-kDa tandem fusion tag enables a range of detection and affinity purification strategies. After cleavage with 3C protease, purified proteins are left with a 4.8kDa C-terminal tag
We provide certain clone resources developed by leading academic laboratories. Many of these resources address the needs of specialized research communities not served by other commercial entities. In order to provide these as a public resource, we depend on the contributing academic laboratories for quality control.
Therefore, these are distributed in the format provided by the contributing institution "as is" with no additional product validation or guarantee.We are not responsible for any errors or performance issues. Additional information can be found in the product manual as well as in associated published articles (if available). Alternatively, the source academic institution can be contacted directly for troubleshooting.
