Microarray expression profiles of STS antigens recognized by autologous IgG antibodies (blue boxes) in 8 subtypes of STS and in normal tissues. Sarc-9/DLG-7 is predominantly expressed in cancer and testes (normal tissue panel in green box). The remaining antigens are variably expressed in cancer and normal tissues. Light to dark color variation represents high to low levels of expression. Affymetrix U133A GeneChip® annotation is indicated at the bottom.
