The present invention relates to a folding process for the preparation of biologically active, dimeric, TGF-&#x3b2; (Transforming Growth Factor type &#x3b2;)-like protein in a detergent-free folding buffer.

Process for the production of biologically active protein

The present invention relates to a folding process for the preparation of biologically active, dimeric TGF-.beta. (Tranforming Growth Factor type .beta.)-like protein.

Process for the production biologically active dimeric protein

The invention relates to a process for the production of biologically active, dimeric TGF-.beta., to novel TGF-.beta.s and pharmaceutical compositions comprising it. TGF-.beta. produced by this process can be used in various therapeutic modalities.

Process for refolding recombinantly produced TGF-.beta.-like proteins

The invention concerns polypeptides with an apparent molecular weight of around 160 kD which are mediators or precursors for mediators of inflammation, derivatives thereof such as mutants and fragments, processes for their preparation, DNAs and hybrid vectors coding for the polypeptides and derivatives and host cells transformed with such hybrid vectors, polyclonal and monoclonal antibodies specific for the polypeptides or their derivatives and antibody derivatives as well as diagnostic and therapeutic methods for inflammatory conditions and Hodgkin lymphomas.

Cytokine which mediates inflammation

The invention concerns polypeptides related to human macrophage migration inhibition factor, in particular the polypeptides called MRP-8 and MRP-14, processes for their preparation, mRNAs, DNAs and hybrid vectors coding for those polypeptides, hosts transformed with such a hybrid vector, monoclonal and polyclonal antibodies to those polypeptides, and diagnostic methods for inflammatory conditions and cystic fibrosis.

DNAS encoding human macrophage migration inhibition factor related

The process for the production of a dimeric, biologically active Transforming Growth Factor type .beta. (TGF-.beta.)-like protein or a salt thereof, comprising refolding the denatured monomeric form of the protein in the presence of a mild detergent that permits folding of the monomeric protein into a spatial conformation, which after dimerization, is the conformation associated with the biological activity, while retaining the monomeric protein in soluble form. Mild detergents include sulfobetaines, 3-(3-chlolamidopropyl)dimethylammonio-1-propanesulfonate, 3-(3-chlolamidopropyl)dimethylammonio-2-hydroxy-1-propane-sulfonate, digitonin, cholate and deoxycholate at a concentration of about 1 to 100 mM. Compositions containing a TGF-.beta.-like protein produced according the invention can be used for the promotion and acceleration of wound healing and bone and tissue repair, cancer treatment, bone marrow protective agent, as a mediator of cardio-protection, as an anti-inflammatory or immunosuppressive agent, or as a growth regulator in mammalian cell cultures.
