The specificity of the affinity purified antibodies for the synthetic peptides and recombinant expressed ASPL-TFE3 type 1 and ASPL-TFE3 type 2 proteins was evaluated by enzyme-linked immunosorbent assay and was highly fusion type specific.     ///    "In this study, polyclonal antibodies were generated to 25 mer peptides encompassing the junctional regions of ASPL-TFE3 type 1 and ASPL-TFE3 type 2. "    ///    Immunohistochemical discrimination between the ASPL-TFE3 fusion proteins of alveolar soft part sarcoma..
