Hello group,
   we are having a hard time with blunt end ligation. We are polishing
ends with pfu polymerase. Any suggestions given that? How sensitive are
ligases to salt concentration? I have read about the use of PEG and seen
reference to a protocol that changes the concentration during the ligation
reaction (first high conc favoring insert+vector, then low favoring
circularization). Any thoughts?
