I am planning to do Bisulfite sequencing but my samples lacks the flanking region upstream and downstream for primer binding. So can anyone help me with possible solutions?
To sequence unknown flanking regions you need to go back to old techniques like chromosome walking or inverse PCR... with the inverse PCR you design a couple of divergent primers next to a known restriction site close to your end, cut your DNA with this enzyme and then make intramolecular ligations to have circular templates. Then you amplify with the primers (now they became convergent) and sequence... I did this technique to determine the cleavage site of the CRISPR system...
Good luck,
