title: [Immunochemical evidence for the specific binding of putrescine to plasma proteins including fibronectin].
abstract: Human plasma contains proteins capable of binding 14C putrescine by the action of Ca++ activated transglutaminase. These proteins have molecular weights from 32 to 220 K and above. One of these (with a molecular weight of 220 K) has been identified as fibronectin by the use of an antifibronectin antiserum. Evidence for a protein with a molecular weight identical to that of fibronectin has been obtained on PAGE analysis of the precipitate formed on incubating human serum with antipolyamine antiserum.
