ABSTRACT:
The invention relates to large latent complexes of TGF-.beta.2 and TGF-.beta.3, and methods for isolating these. The complex consists of a dimerized form of TGF-.beta.2 or TGF-.beta.3, the appropriate latency associated peptide, and the latent TGF-.beta.1 binding protein, referred to as LTBP. Also described is a protein which binds to all of TGF-.beta.1, TGF-.beta.2 and TGF-.beta.3, but is immunologically distinct from LTBP, referred to as LTBP-2.
