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 shotgun mutagenesis epitope mapping. [ 2 ] [ 10 ] [ 30 ] Shotgun mutagenesis is a high-throughput approach for mapping the epitopes of mAbs. [ 30 ] The shotgun mutagenesis technique begins with the creation of a mutation library of the entire target antigen , with each clone containing a unique amino acid mutation (typically an ...
Chemogenomics Staubli robot retrieves assay plates from incubators. Chemogenomics, or chemical genomics, is the systematic screening of targeted chemical libraries of small molecules against individual drug target families (e.g., GPCRs, nuclear receptors, kinases, proteases, etc.) with the ultimate goal of identification of novel drugs and drug targets. [1]
As above mentioned, combinatorial chemistry was a key technology enabling the efficient generation of large screening libraries for the needs of high-throughput screening. However, now, after two decades of combinatorial chemistry, it has been pointed out that despite the increased efficiency in chemical synthesis, no increase in lead or drug ...
Hit to lead (H2L) also known as lead generation is a stage in early drug discovery where small molecule hits from a high throughput screen (HTS) are evaluated and undergo limited optimization to identify promising lead compounds.
In yeast two-hybrid screening, separate bait and prey plasmids are simultaneously introduced into the mutant yeast strain or a mating strategy is used to get both plasmids in one host cell. [9] The second high-throughput approach is the library screening approach. In this set up the bait and prey harboring cells are mated in a random order.
The tandem affinity purification (TAP) method allows the high-throughput identification of proteins interactions. In contrast with the Y2H approach, the accuracy of the method can be compared to those of small-scale experiments (Collins et al., 2007) and the interactions are detected within the correct cellular environment as by co-immunoprecipitation.
Advanced development of 3D models for high-throughput screening in high density formats has recently been achievable due to technological achievements related to increased microplate density. These can be found in 384 and 1536-well formats that are cell repellent, cost effective, and amenable to fully automated screening platforms. [69]
