Abstract
A heterodimeric form of TGF-.beta. is described. This 25 KD molecule is active in an in vitro assay of inhibition of epithelial cell growth. The protein may be isolated from bone. When reduced, the protein elutes in two peaks by RP-HPLC. In immunoblots, the reduced protein from the earlier eluting peak reacts predominately with antibodies directed against TGF-.beta.3, while reduced protein from the later eluting peak reacts predominately with antibodies directed against TGF-.beta.2. The N-terminal amino acid sequence and immunoreactivity of the native protein are consistent with a heterodimer of TGF-.beta.2 and TGF-.beta.3.
