Abstract: A method for the separation or purification of biopolymers comprises adsorbing the biopolymer on the surface of liquid oil droplets; and separating the adsorbed biopolymer from the oil droplets. The adsorbed biopolymer is separated from the oil droplets by mixing the droplets in an aqueous liquid, removing the lower aqueous phase and adding a fresh aqueous phase to the droplets, cooling the mixture to solidify and coalesce the oil and to cause it to release the adsorbed biopolymer to the fresh liquid, separating the fresh liquid and the biopolymer from the coalesced oil, separating the biopolymer from the fresh liquid.

Abstract: A method for stimulating integumental melanocytes by the topical application of alpha-MSH analogs, and compositions comprising said analogs for use in the method are described.

Abstract: Macromolecular monoclonal antibody compositions are provided which are capable of selectively forming stable bonds to cells having a predetermined concentration of at least one surface antigen, such concentration being greater in such cells than in other cells in the cell population, wherein the composition comprises a substrate and a plurality of monoclonal antibodies specific to said surface antigen or antigens, which antibodies are covalently bonded to the substrate.

Abstract: The invention concerns novel renin-inhibiting peptides which are modified as isosteres. These peptides are useful for treating renin-associated hypertension and hyperaldosteronism. Processes for preparing the peptides, compositions containing them and methods for using them are included. Also included is a diagnostic test using the peptides to determine the presence of renin-associated hypertension or hyperaldosteronism.

Abstract: Novel biologically active polypeptides, including a new class of transforming growth factor (TGF) polypeptides, which exhibit cell growth promoting properties are disclosed, as well as a process for isolating the TGF polypeptides from both human and murine cell lines in homogeneous form. Also disclosed are antigenic oligopeptides derived from the TGF polypeptides and antibodies raised therefrom which have application in the detection and treatment of malignancies and oligipeptides which have the ability to bind with cellular growth factor receptors and thus to interfere with transformation of certain cell lines into a cancerous state. Compositions and methods based on the disclosed peptides for detection and treatment of cancer and other proliferative diseases and for cell or tissue growth associated treatment, e.g., wound healing, ulcer therapy and bone loss are also described.

Abstract: The present invention provides novel renin-inhibiting peptides of the formula X-A.sub.6 -B.sub.7 -C.sub.8 -D.sub.9 -E.sub.10 -F.sub.11 -G.sub.12 -H.sub.13 - I.sub.14 -Z, wherein the E.sub.10 -F.sub.11 moiety is a dihydroxyethylene isostere, X and Z are terminal groups, and the remaining variables are absent or are amino acid residues.
