TM) during the annealing step. It is added at the sequencing reaction stage. The presence of ss binding protein also helps. I must admit that I prefer to reclone into M13, but direct sequencing is useful if you just want to check a short region. Hope this helps, Jim Brannigan BAFM1@UK.AC.SUSSEX.CLUSTER
