ToffOligo

Select oligonucleotide configuration:
Oligo hybridized to its template Fork blocking Apex of an hairpin
Define the oligonucleotide sequence, typically in upper case. If you are specifying an RNA or LNA oligonucleotide, indicate bases of this type by upper case, use lower case for DNA base. If you want to introduce mismatches select the use template option and define the template otherwise leave template blank
Oligo sequence 5'to 3' (example ACGTGCT)- Use template Template 3'to 5' (only if Use template is checked)
5'--3' 3'--5'
Select oligonucleotide type (template is DNA in all cases):
DNA Oligo RNA/dna oligo LNA/dna oligo
