Abstract: The invention provides improved sample preparation techniques as will as improved methods of analysis of samples. The techniques include a method of preparing a sample of MALDI-TOF analysis comprising applying a material having a liquid component to a carrier, removing at least a portion of the liquid component, and applying a MALDI matrix over the material to be analysed. In other embodiments, the sample preparation techniques include digestion of peptides prior to analysis by MALDI-TOF, which may be done in the presence of a surfactant, and sandwiching a sample for analysis between layers of MALDI matrix on a sample carrier.

Abstract: Peptides immunologically related to proteins expressed by a viral agent, having a sequence of amino acids ordered by means of the protein informational analysis techniques using the Fourier transform method with reference to the amino acid sequence of a target antigen against which antibodies are desired to be formed, or lymphocytes desired to be directed. The sequence has in the Fourier spectrum, one or more frequencies of practically the same value as the frequency of frequencies characteristic of the target antigen.

Abstract: Polypeptides exhibiting an inhibitory action over follitropin are disclosed. These polypeptides are designated follitropin suppressing proteins, or "FSP's," and range in size from 30 to 60 kD as determined by SDS-PAGE. Uses for FSP's, including regulation of fertility and as immunogens, are disclosed.

Abstract: 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.

Abstract: 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.
