Yeast Two-Hybrid Assay to Determine Protein Self-Association in Yeast Cells

2025
This video demonstrates the yeast two-hybrid assay to detect specific protein self-interactions. In this assay, the protein of interest is tagged to two domains of a transcription factor that encodes the β-galactosidase enzyme. When the two proteins interact, this causes transcription and translation to form the enzyme, which is then detected using a biochemical assay.

We describe a rapid and effective method for purification of mitochondria from the yeast Saccharomyces cerevisiae. This method enables the high-yield isolation of pure mitochondria that are essentially free of contamination by other organelles and retain their structural and functional integrity after their purification.

Research performed in the yeast Saccharomyces cerevisiae has significantly improved our understanding of important cellular phenomona such as regulation of the cell cycle, aging, and cell death. The many benefits of working with S. cerevisiae include the facts that they are inexpensive to grow in the lab and that many ready-to-use strains are now commercially available. Nevertheless, proper maintenance of this organism is critical for successful experiments. This video will provide an overview...

Saccharomyces cerevisiae is a species of yeast that is an extremely valuable model organism. Importantly, S. cerevisiae is a unicellular eukaryote that undergoes many of the same biological processes as humans. This video provides an introduction to the yeast cell cycle, and explains how S. cerevisiae reproduces both asexually and sexually Yeast reproduce asexually through a process known as budding. In contrast, yeast sometimes participate in sexual reproduction, which is important because...
FAQs
Porous gels provide spaces that retain yeast while remaining accessible to dissolved substances. Nutrients can move into these spaces to support cellular activity, and products or other dissolved molecules can move out. This balance matters because effective confinement must preserve molecular exchange needed for fermentation rather than isolate cells from their environment.
Adsorption and chemical binding represent two surface-based ways to associate yeast with a support. Adsorption associates cells with a surface, whereas chemical binding associates them through a chemical linkage. Comparing these arrangements helps researchers examine how cells are retained while preserving access to nutrients and removal of products.
High local concentration keeps a substantial yeast population associated with the process rather than dispersed for recovery after each run. That feature can support repeated-batch or continuous fermentation, while the support simplifies cell recovery. The result connects the spatial organization of cells with goals of process stability and operational efficiency.
A general workflow begins by selecting a supporting material and an arrangement, such as entrapment in a porous gel or attachment to a surface by adsorption or chemical binding. The prepared system is then used for fermentation or biocatalysis, with dissolved-molecule exchange maintained during operation. Because cells remain associated with the support, recovery and reuse can follow.
Yeast cell immobilization is useful when a process benefits from retaining cells for more than one operating cycle. Its applications include bioethanol production, food fermentation, and biocatalysis, where simplified recovery, reuse, process stability, and operational efficiency are relevant. The same approach also provides a biological engineering framework for studying yeast metabolism under supported conditions.
Within biology, immobilized yeast can be used to investigate cellular metabolism while the cells remain associated with a defined support. Researchers can relate metabolic activity to the surrounding arrangement and to the movement of nutrients and products through that system. This links cell-level questions with engineering variables such as retention, recovery, and repeated operation.
