  • Patent number: 5650494
    Abstract: 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.

  • Patent number: 5650513
    Abstract: Reacting the industrially readily available perylene-3,4,9,10-tetracarboxylic dianhydride (3) with specific primary amines in the presence of water gives perylene-3,4-dicarboxylic bisimides (2). Their hydrolysis affords the perylene-3,4-dicarboxylic anhydride on a preparative scale, and this anhydride is reacted with any primary amines to give likewise the corresponding imides 2. Condensation of the anhydride with diamines results in novel types of dyes, namely perylene-3,4-dicarboxamidines which have very good fastness properties. Also claimed are specific perylene-3,4-dicarboxylic diesters, perylene-3,4-dicarboxylic ester amides, perylene-3,4-dicarboxamidines and perylene-3,4-dicarbonyl derivatives, processes for preparing these compounds and their use.

  • Patent number: 5648509
    Abstract: The addition of acid diesters of phosphorous acid onto alpha,beta-unsaturated carboxylic acid derivatives under basic catalysis is achieved with good yields if it is carried out in the presence of alkali metal alcoholates or phenolates and in the presence of halides, oxides or hydroxides of divalent metals. Co-use of these metal compounds allows relatively small mounts of metal alcoholates or phenolates to be used. The resulting reaction mixtures do not contain relatively large amounts of troublesome by-products.

  • Patent number: 5645169
    Abstract: A package containing water-soluble bags filled with agricultural chemicals in gel or liquid form facilitates the transport of the bags in a manner which prevents the breakage thereof. The package includes compartments for holding the bags. The walls and base of these compartments contain raised and unraised portions in a pattern such that a baffling effect is created to damper transport shock waves in the gel or liquid bag. These and other features result in the transmission of dynamic shock loads in the package in a manner which prevents such shock loads from breaking the fragile water-soluble bags during transport.

  • Patent number: 5645973
    Abstract: A process is described for the preparation of photopolymerizable compositions, wherein the photopolymerizable compositions can be photopolymerized by the irradiation of emission lines of differing wavelength from a UV/VIS laser light source, and contain a photopolymerizable compound and at least two photoinitiators, by adjusting the sensitivity to radiation. The ratio between the concentrations of the individual photoinitiators is so adjusted that the composition has virtually the same optical density for the radiation of the different emission lines at which the photoinitiators are effective.
