Genetic Screens - Chemical Mutagenesis Service

Mutagenesis can be induced by a variety of chemical agents, with a specific array of favored lesions and mutation frequencies. Chemical mutagenesis is a whole-genome profiling of mutagenesis for forward genetic screens and target-selected mutagenesis. This approach is the easiest and most straightforward way to be scaled up for systematically inducing germline mutations at high frequency, providing a new strategy for the breeding of new varieties and the establishment of animal models of diseases.

The genome sequencing of C. elegans has been achieved. Moreover, because of its hermaphroditism, severe mutations can be maintained homozygously in the population and hence their propagation through self-fertilization. Thus C. elegans is optimal for studying thoroughly the characteristics of each gene to get insights into the cellular processes. We offer chemical mutagenesis services in C. elegans.

High-throughput mutagenic platform

We provide a rapid and scalable platform for high-throughput screening to identify mutants with two widely used chemical mutagenesis. The C. elegans growth, mutagenic procedure, screening, and mutant recovery are all in 96-well microtiter plates.

Available service

C. elegans EMS mutagenesis service

Ethyl methanesulfonate (EMS) is an alkylating agent, and its mutagenic properties were first demonstrated using the T4 viral system in 1959. With its relatively low toxicity and relatively good efficiency, EMS is the most commonly used chemical mutagen to mutate the genome of C. elegans and the most potent at the present.

C. elegans ENU mutagenesis service

The chemical N-ethyl-N-nitrosourea (ENU) is an alkylating agent, and has been used as a mutagen since the 1970s and for C. elegans mutagenesis in 1997. Compared to EMS, ENU has been shown to produce a different spectrum of mutations, especially for the production of non-null alleles, and it has greater toxicity to C. elegans. Its toxicity can be reduced in solvents such as absolute ethanol, and increased in aqueous solutions.

Method Types Forward Mutation Rate The mutation spectrum Main Targets Purposes
Chemical mutagenesis EMS as high as 2.5 × 10−3 mutations/gene/generation Primarily G/C to A/T transitions the sperm and oocytes Forward genetic screens, target-selected mutagenesis
ENU approximate rate of 1 per 700 gametes (Point Mutations Rate) A/T to T/A transversions, G/C to A/T transitions, and A/T to G/C transitions spermatogonial stem cells
