Chemical-genetic approaches are based on measuring the cellular outcome of combining genetic and chemical perturbations in large-numbers in tandem. In these approaches, Creative Biolabs evaluates the biocompatibility of different genes by contacting different chemicals. Our state-of-the-art technology enables chemical genetics to be applied to a wide range of physical samples with great efficiency, helping customers promote their drug development projects.
Chemical genetics generally refers to a systematic assessment of the effects of genetic variation on drug activity. Chemical genetics was first established in the field of microbiology and is now increasingly used in human cell lines. As more and more experimental tools are developed, our chemical genetics related services can assist in the development of drugs in a number of ways, including identification of Mode-of-Action (MoA), mapping of uptake and efflux routes, revealing of resistance mechanisms and understanding of interactions with other drugs. Similarly, chemical genetics can also be analyzed in array libraries using experimental automation and image processing software. Hundreds of thousands of mutants can be analyzed in the same plate. In the array form, the effects of drugs can be evaluated by other macroscopic phenotypes other than growth, such as biofilm formation, spore formation, DNA uptake, or cell lysis. Although microbial chemical genetic screening focuses on measuring the overall phenotype, with the recent developments in high-throughput microscopy, it is also possible to quantify single-cell phenotypes and population behavior in mutant libraries. In this case, the cellular markers and classifiers of the drug response can further understand the biological activity of the drug in the cell.
