RT-PCR analysis. Electrophoresis gel shows 100 bp size marker (L), HPRT housekeeping gene control (H), extracted RNA of the patient's tumor (P), RNA of SS with cytogenetically proven t(X;18)(p11;p11) (+), and H2O as negative control (−). Patient's cDNA and positive control show a product in the expected range of 585 bp.
