Screening with the Yeast 2-Hybrid System on iQue
29 Jul 2015The Y2H screening system is a protein-fragment complementation assay that uses the power of molecular biology to screen for protein-protein (PPI) and protein-DNA (PDI) interactions. Traditional Y2H assays brought the bait and prey yeast strains together on solid agar that would turn blue when the LacZ reporter enzyme was expressed. The colonies expressing the reporter protein were picked off the surface and cultured. This process is effective, but the color development is slow and the colony picking is tedious. This application note describes how the Y2H system is readily adapted to the iQue by changing 2 aspects of the traditional system.

High-Throughput ScreeningHigh-throughput screening (HTS) is an automated drug discovery technique for identification of active compounds against a compound library. Use HTS readers and integrated assay preparation / analysis workstations to screen your compounds. Identify active compounds against various HTS libraries, including membranes, proteins and peptides and HTS cell lines. Find the best high-throughput screening products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.High-Content ScreeningHigh-content screening (HCS), also known as high-content analysis (HCA), is a high-throughput technique used in drug discovery to identify substances that alter the phenotype of cells. HCS uses fluorescent microscopic imaging and automated image analysis to investigate cellular events such as apoptosis, cell viability, GPCR activation, oxide production, neurite outgrowth, and cell signaling.

Software is used for analysis of ADME results, toxicology, clinical trials and regulatory processes. ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Screening SystemDNADeoxyribonucleic Acid (DNA) is the main component of chromosomes and the carrier of genetic information of living organisms. Find out here about PCR, NGS, ChIP-Seq, gel imaging, and many other techniques which can be used for the analysis of DNA.Cell AnalysisThe analysis of cells allows researchers to understand the factors which contribute to cell health and function. These influencing processes can then be predicted and altered, leading to the development of medication and disease treatments.Protein InteractionsProtein interactions are essential for understanding cellular processes, as proteins work together to carry out biological functions. Studying protein interactions can provide insights into disease mechanisms, drug development, and cell signaling pathways.
