further analysis of conditioned media with antiserum to either a pro- [ amino acid ( aa ) residues 1-220 ] or mature [ aa 297-414 ] peptide of the tgf-beta 2 precursor suggests that tgf-beta 2 , similar to tgf-beta 1 production in chinese hamster ovary cells [ gentry et al. , mol . cell . biol . 7 ( 1987 ) 3418-3427 ] , is initially synthesized as a larger precursor protein which is proteolytically cleaved to yield the mature 112-aa transforming growth factor .
