analysis of translation products by sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed ( 1 ) very little synthesis of proline-rich proteins from poly ( a+ ) rna of glands of normal rats , ( 2 ) poly ( a+ ) rna from glands of treated animals synthesize mainly proline-rich proteins , ( 3 ) translations with [ 3h ] proline and [ 35s ] methionine give identical labeling patterns from cell-free translations are all precipitated by antibodies to proline-rich proteins .
