RT-PCR on three different t(X;1)-positive RCCs
(lanes 1–3) and t(X;1)-negative controls (lanes 4–6). Lanes: 1,
CL89-12117; 2, CL89-17872; 3, RP-T; 4, RP-N; 5, normal renal tissues
pooled from several persons; and 6, normal renal tissue from a patient
with RCC. The marker shown is the 100-bp ladder (Life Technologies).
All three RT-PCR products showed the same sequence joining 150 bp of
TFE3 to 48 bp of EST R93849R93849.
