Search for potential TFO target sequences:
1. Select species.
   Species   
2. Use the popup list to select to search by gene description, gene name (i.e. symbol), or Entrez Gene ID
   and then enter search criterion in the text box. You can use an asterisk (*) as a wildcard if you wish
   to perform a non-exact search on gene name. Gene description searches are always non-exact
   and the criterion is treated as a phrase.
