• Enter a nucleotide sequence in IUPAC format and click the search button
• A variable-length consensus sequence may also be entered in a format to reflect the unknown number of nucleotides

Example: GTAN{3,5}AGTN{5,10}AGTC

In this example any nucleotide can appear 3 to 5 times startingat position 4 and any nucleotide can appear 5 to 10 times starting at the position following the T
