Description

Includes

The ProQuest Two-Hybrid System includes yeast expression vectors pDEST32, pDEST22, and pEXP-AD502 for generation of GAL4 DNA Binding Domain and GAL4 Activation Domain fusion proteins, and LR Clonase II Enzyme Mix, a glycerol stock of the MaV203 yeast strain, as well as positive and negative controls for the two-hybrid assay.

An in vivo yeast-based system for identifying interactions between two proteins

  • Reconstitutes a functional transcription factor that activates chromosomally integrated reporter genes where transcriptional activation is monitored by the growth of cells on selective media
  • Allow rapid and easy generation of bait and prey constructs, and facilitate downstream application
  • Low copy-number DBD (DNA Binding Domain) and AD (Activation Domain) vectors (ARS/CEN) to control over-expression and increase reproducibility
  • Three different reporter genes (HIS3, URA3, and lacZ) with independent promoter regions to rapidly weed out false positives
  • URA3 reporter gene allows for both positive and negative selection, enabling advanced two-hybrid techniques such as reverse two-hybrid
  • A set of strong-to-weak Gateway-based control interactions to evaluate results and assess the strength of the interaction being tested
