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.

How it works

ENU mutagenesis creates modified DNA bases by transferring its ethyl moiety to nitrogen or oxygen on any of the four nucleotides, which then hinders proper replication. Because of equal mutation of all codons with ENU, non-null alleles are often generated.

Properties and advantages of ENU mutagenesis

  • ENU is a member of the alkylating agent class of mutagens and has a preference for A/T to T/A transversions, G/C to A/T transitions, and A/T to G/C transitions.
  • The point mutations occur at an approximate rate of 1 per 700 gametes, and at approximately 1-2 Mb intervals.
  • ENU may be a much more useful mutagen, especially for the production of non-null alleles.
  • ENU mainly targets spermatogonial stem cells.
  • ENU is a superior mutagen for genetic studies of protein function and protein–protein interaction, such as suppresser screens.

Available services
