An Alternative to Two-Hybrid
Aileen Constans | Oct 28, 2001 | 2 min read
Researchers most often use techniques such as coimmunoprecipitation and yeast two-hybrid screening to study protein-protein interactions. These methods are time-consuming-the yeast two-hybrid technique can take several months to perform-and prone to false positive results. Millbury, Mass.-based Hypromatrix recently introduced AntibodyArray™ technology to combat these problems. Hypromatrix developed the AntibodyArray for the study of protein-protein interactions and protein phosphorylation,

The Two Body Problem

Two-Hybrid Systems Studying a biological phenomenon? Which field? Well, it really doesn't matter. Whatever the area of interest, rest assured that protein-protein interactions are somehow, somewhere involved--if not directly, then as part of a structural or regulatory apparatus. Two-hybrid systems, pioneered by Fields and Song,1 are powerful systems for detecting interactions between and among macromolecules. The first systems described were for protein-protein interactions; later, the basic
Turn Up the Lex Appeal

Schematic illustration of the LexA-based yeast two-hybrid interaction. Source: OriGene Technologies, Inc. 97/98 Catalog. Reprinted with permission. The DupLEX-ATM system from OriGene Technologies is a LexA-based two-hybrid assay for the detection of protein-protein interactions in vivo (J. Gyuris et al., Cell 75:791-803, 1993). The LexA system is conceptually similar to the prototypical GAL4-based two-hybrid system, both of which are based on the bipartate nature of yeast transcriptional acti

A Test Bed for Budding Technologies

DELETION BY DESIGN:Courtesy of Guci GiaeverThe deletion cassette module used to delete each yeast gene contains two 74-basepair tags upstream and downstream (UPTAG and DNTAG) of the KanMX gene, which confers resistance to the drug geneticin. UPTAG and DNTAG contain 18 basepairs of genomic sequence to flank the yeast's open reading frame, and U1 and U2, or D1 and D2 PCR primers for amplifying a unique 20-basepair TAG region-the so-called molecular barcode. A second round of PCR adds 45 base-pairs
