Figure 2.

A: Immunoblot showing a single ∼110-kd band in the KG1a control lysate (lane 1), solitary fibrous tumor (case 4; lane 3), malignant GIST (case 2; lane 5), myofibroblastoma (lane 6), and spindle cell lipoma (case 12; lane 7), a broad smear at somewhat lower molecular weight in epithelioid sarcoma (nonmicrodissected, see text; lane 2), and lack of a band of similar mobility in CD34 immunohistologically nonreactive malignant GIST (case 3; lane 4). Lanes 1 and 2 are from the same immunoblot; lanes 3–7 are taken from separate experiments. All SDS-PAGE analyses were performed with standard protein molecular weight markers and the KG1a control lysate to facilitate comparison of electromobility of the proteins in separate experiments. B: Immunoblot showing a single ∼110-kd band in KG1a control lysate (lane 1) and in the DFSP from the leg (case 8; lane 2). The DFSP from the breast (case 7) shows double bands that span the thickness of the single bands (lane 3).
