High-content screening where changes in the expression of several proteins can be simultaneously monitored is also often used. [9] [10] High-content imaging of dye-labeled cellular components can also reveal effects of compounds on cell cultures in vitro, distinguishing the phenotypic effects of a broad variety of drugs. [11]
High-throughput screening (HTS) is a method for scientific discovery especially used in drug discovery and relevant to the fields of biology, materials science [1] and chemistry. [ 2 ] [ 3 ] Using robotics , data processing/control software, liquid handling devices, and sensitive detectors, high-throughput screening allows a researcher to ...
High-throughput phenotypic testing is increasingly important for exploring the biology of bacteria, fungi, yeasts, and animal cell lines such as human cancer cells.Just as DNA microarrays and proteomic technologies have made it possible to assay the expression level of thousands of genes or proteins all a once, phenotype microarrays (PMs) make it possible to quantitatively measure thousands of ...
Given the increase in the use of phenotypic/visual screening as a cell biological tool, methods are required that permit systematic biochemical target identification if these molecules are to be of broad use. [6] Target identification has been defined as the rate limiting step in chemical genetics/high-content screening. [7]
Classical High throughput screening robotics are now being tied closer to cell biology, principally using technologies such as High-content screening.High throughput cell biology dictates methods that can take routine cell biology from low scale research to the speed and scale necessary to investigate complex systems, achieve high sample size, or efficiently screen through a collection.
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
Protein–protein interaction screening refers to the identification of Protein–protein interaction with high-throughput screening methods such as computer- and/or robot-assisted plate reading, flow cytometry analyzing. The interactions between proteins are central to virtually every process in a living cell.
For one, the high off-target effects cause issues with false-positive observations. [20] [21] Additionally, because RNAi reduces gene expression at the post-transcriptional level by targeting RNA, RNAi-based screens only result in partial and short-term suppression of genes. Whilst partial knockdown may be desirable in certain situations, a ...
