all antisera reacted only with a restricted region of the alpha-tgf corresponding to the 8 residues ( 43-50 ) at the carboxy-terminus : ( formula ; see text ) a series of synthetic peptides representing deletions or substitutions of amino acids in this carboxy-terminal region were tested for competition with 125i-alpha-tgf .
