Receptor-binding cancer antigen expressed on SiSo cells can be detected in metastatic lymph nodes from gastrointestinal cancers

Figure 2 Nucleotide sequence alignment of RCAS1 cDNA from databases present at NCBI GenBank (gi: 13528905) and RT-PCR products from metastatic lymph nodes. The residues boxed in black indicate positional identity for both sequences. Numbers of nucleotide sequences are indicated on the left and right margins.
