-
↵Linker sequences removed from our SAGE libraries were TCCCTATTAA and TCCCCGTACA.
-
↵Upon examination of several duplicate DiTags in the limb SAGE libraries, all were found to be composed of high abundance SAGE Tags (data not shown), indicating that the duplicate DiTags in these SAGE libraries were not due to DiTag amplification bias.
-
↵For an explanation of this value, in the context of the quality of a SAGE library, see Margulies et al. (2001).
