Fluorescent PCR to detect a MMTV-like sequence in feline lymphomas. A Fragment analyses show the blue peaks at 191 bp that represent the size of the amplified env fragment in sample #90722, DM B-type nasal lymphoma. B Fragment analyses show the blue peaks at 191 bp (red arrows) that represent the size of the amplified env fragment in sample #93602, SNC B-type gastrointestinal lymphoma. C Agarose gel electrophoresis (2%) of PCR products with a target size of 201 bp. (M): molecular weight marker; (1): ID #90722, DM B-type nasal lymphoma; (2): ID#92134, DM T-type gastrointestinal lymphoma; (3): ID#92644, DSL B-type nasal lymphoma; (4): ID#91221, DL B-type gastrointestinal lymphoma; (5): ID#93602, SNC B-type gastrointestinal lymphoma; (−) negative control; (+) positive control
