From: Incidence of "quasi-ditags" in catalogs generated by Serial Analysis of Gene Expression (SAGE)
Raw SAGE sequence data showing cloning and potential sequencing artifacts not excluded by SAGE software. (A) Clone with fragment of E. Coli genomic DNA. Italics denote E. Coli sequence (AE000307). (B) Clone with unidentifiable insert, which lack normal SAGE concatemer. Sequences like (A-B) represent quasi-ditags that should have been removed. pZErO-1 sequence is underlined; Anchoring enzyme recognition sites (AERS(CATG)) are shown in bold, and potential SAGE tags are shown by dotted underlines.
