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 ...
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.

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 ...
Unlike high-content analysis, high-content screening implies a level of throughput which is why the term "screening" differentiates HCS from HCA, which may be high in content but low in throughput. In high content screening, cells are first incubated with the substance and after a period of time, structures and molecular components of the cells ...
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.
Following phenotypic selection, genomic DNA is extracted from the selected clones, alongside a control cell population. [ 23 ] [ 46 ] [ 49 ] In the most common protocols for genome-wide knockouts, a 'Next-generation sequencing (NGS) library' is created by a two step polymerase chain reaction (PCR).
Phenotypic screening is characterized by the process of screening drugs using cellular or animal disease models to identify compounds that alter the phenotype and produce beneficial disease-related effects. [54] [55] Emerging technologies in high-throughput screening substantially enhance processing speed and decrease the required detection ...
