• 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: AGN{2,4}AW{1,3}TAG

In this example any nucleotide can appear 2 to 4 times starting at the position 3 and A or T can appear 1 to 3 times starting at the position following the A

IUPAC format

• A = adenine
• C = cytosine
• G = guanine
• T = thymine
• U = uracil
• R = G A (purine)
• Y = T C (pyrimidine)
• K = G T (keto)
• M = A C (amino)
• S = G C
• W = A T
• B = G T C
• D = G A T
• H = A C T
• V = G C A
• N = A G C T (any)
