In the protocol entitled 'Using formaldehyde-assisted isolation of regulatory elements (FAIRE) to isolate active regulatory DNA,' we described how to perform FAIRE from cultured cell lines and mammalian tissues1. In this addendum, we compile a list of species and cell types in which FAIRE has been successfully performed according to a published report. This survey confirms that the FAIRE protocol, typically with only minor modification, is applicable to animals, plants, fungi, protists and viruses. Please note that this survey was performed manually, and so it is possible that our list of species and publications is not complete. We apologize for any omissions. Our hope is that by compiling this list, scientists who may wish to use FAIRE in the cell types or species below may refer to the listed papers for any modifications required to our protocol. There are several notable experimental systems for which we could not find published reports of FAIRE data, including Caenorhabditis elegans, Tribolium (flour beetle), zebrafish, Xenopus and sea urchin. Although we suspect that FAIRE will be effective in these systems, it is always possible that special modifications to the FAIRE protocol will be required. If you are having trouble getting FAIRE to work in your system, we welcome any inquiries.
