Ordering Information

The yeast Saccharomyces cerevisiae (S. cerevisiae) is a recognized simple eukaryote model system which genome can be easily manipulated. The S. cerevisiae VN-Fusion Library was created by Dr. Won-Ki Huh of Seoul National University (Korea).
The VN-Fusion Library consists of 5,809 VN-tagged Open Reading Frames (ORFs) covering 93% of the yeast proteome.


Bimolecular Fluorescence Complementation (BiFC) assay

Most biological processes are carried out and regulated by dynamic networks of protein-protein interactions. The Bimolecular Fluorescence Complementation (BiFC) assay is now regarded as one of the most advanced and powerful tools for studying in vivo detection of protein–protein interactions in several orgarnisms. The BiFC assay is based on the formation of a fluorescent complex by fragments of yellow fluorescent protein, brought together by association of two interacting partners fused to the fragments. This approach enables visualization of the subcellular localizations of specific protein complexes in the normal intracellular environment.
