BAT 25 and BAT 26 PCR products for two medullary carcinomas, a conventional adenocarcinoma, and normal pancreas. For both the BAT 25 and BAT 26 PCR products: lane 1, pancreatic medullary carcinoma with a microsatellite shift; lane 2, normal pancreas from the same patient; lane 3, a different pancreatic medullary carcinoma without a shift; and lane 4, a conventional ductal adenocarcinoma without a shift. The shifting medullary carcinoma and the normal pancreas are both from the patient with synchronous pancreatic and colonic carcinomas.
