Design and Building of Custom-TALENs

Transcription Activator Like Effector Nucleases (TALENs) are tools described recently that perform cleavage of genomic DNA at a precise location. Once cleaved, DNA gets repaired by either of the two mechanisms: A more common Non-Homologous-End Joining (NHEJ) mechanism a less common Homology Directed Recombination (HDR) mechanism. NHEJ process has been harnessed to create knockout cells or organisms since NHEJ almost always leads to either loss or gain of few base pairs near the cut site.

We offer services related to design and building of custom TALENs for any gene using a Golden Gate TALEN assembly protocol Cermak, et al., 2011 (

The details of the service:

  • Bioinformatic analysis of the genomic locus and designing of multiple TALEN binding targets
  • Building of a pair of custom TALENs for the selected target sequence
  • Sequence confirmation of the custom TALENs
  • Consultation on how to use TALENs
