    摘要： The invention relates to the carbonylation of cross linked substituted and unsubstituted polysaccharides, their copolymers with macroporous synthetic polymers, macroporous synthetic polymers and rigid supports with pendant hydroxyalkyl groups. The carbonylated product can be used to prepare an affinity chromatography matrix which remains an uncharged species at varying pH's. The carbonylated product is also useful for the preparation of other compounds: Typical polysaccharides are agarose, starch, dextran, cellulose and regenerated cellulose, typical macroporous synthetic polymers are acrylamides, acrylates and methacrylates, typical rigid supports are silica beads coated with hydroxy alkyl groups and typical cabonylating agents are N,N'-carbonyl diimidazole; N,N'carbonyl di-1,2,3-benzotriazole; and N,N'-carbonyl di-1,2,4-triazole.

    摘要： Methods are described for the generation of natural pH gradients in layers of granulated gels using mixtures of amphoteric or amphoteric non-amphoteric buffer reagents. Because of the favorable characteristics of these flat bed systems, high voltage gradients (20-50 V/cm) can be used for the electrofocusing experiments. Linear or step pH gradients can be formed depending on the choice of buffer system used. Buffer systems, suitable for the preparative electrofocusing of proteins over the pI ranges of 4.0-6.0, 4.5-8.0, 5.0-8.5 and 6.0-8.5 are described.

    摘要： A protein which satisfies all the biological criteria which are characteristic of inhibin has been isolated from a gonadal source. The purification and characterization of inhibin and the use of the purified material to raise antibodies, the use of inhibin and said antisera in a quantative radioimmunoassay, and application in vitro and in vivo of inhibin and antibody to inhibin, are described. There is provided a purified protein, inhibin characterized in that the apparent molecular weight as determined by SDS-PAGE is 56,000.+-.1,000, the isoelectric point is in the range 6.9-7.3, and the protein can bind specifically to Concanavalin A-Sepharose. Moreover, the protein includes two subunits, characterized in that their apparent molecular weights as determined by SDS-PAGE are 44,000.+-.3,000 and 14,000.+-.2,000, respectively. Furthermore, the isoelectric point of the 44,000 molecular weight sub-unit is in the range of 6.0-7.0. In addition, the N-terminal amino acid sequence of the two subunits are described. With regard to the purified protein, inhibin, the protein can suppress follicle stimulating hormone (FSH) but not luteinizing hormone (EACH), thyroid stimulating hormone or prolactin in an in vitro bioassay system, and the protein can be labeled with radioactive iodine. In addition to the forgoing, there is also provided a method for isolating and purifying inhibin from mammalian ovarian follicular fluid, characterized by one or more gel permeation chromatography steps; reversed-phase high performance liquid chromatography steps; preparative polyacrylamide gel electrophoresis steps; and electrophoretic elution of the purified inhibin.
