The present method relates to the serological detection of herpes simplex virus type 2 (HSV-2) infection by means of reaction of a patient serum with a peptide specific to HSV-2 having the sequence Ala-Arg-Ser-Pro-Glu -Arg-Gln-Glu-Pro-Arg-Glu-Pro-Glu. The peptide may be further modified by the addition of a Cys or a biotin molecule. The peptide may be used in any of a number of assays including enzyme linked immunosorbent assay (ELISA), a radioimmunoassay (RIA), and other forms of immunoassay such as enzyme immunoblotting assay on a suitable adsorbent paper or an agglutination assay using the peptide composition as the antigen.
摘要:
Synergistic mixtures of a zeolite and an imide provide superior relief from objectionable odors. The compostions are especially effective to remove the odor of animal wastes or fluids. The mixture may be sprinkled on dogs, dog bedding, horse stalls, animal vomit, urine deposits, fish remains, fish juices and the like. The zeolite/imide mixture will also remove odors from carpets, clothes, hands or other body parts, cloth and plastic items.

This invention discloses slow release formulations for use in application of volatile insect repellents. A copolymer of polyvinyl pyrrolidone and an alkyl group of 4-30 carbons provides the slow release properties. The formulations are characterized by high residual action, low skin penetration, and high resistance to removal by water.
摘要:
Copolymers of polyaspartic acid which are suitable for the Inhibition of scale deposition were obtained by reacting maleic acid, an additional polycarboxylic acid and ammonia in a stoichiometric excess, at 120.degree.-350.degree. C., preferably 180.degree.-300.degree. C., to provide copolymers of polysuccinimide. In a second embodiment, a polyamine was added to the reaction mix. These intermediate polysuccinimide copolymers could then be converted to the salts of copolymers of polyaspartic acid by hydrolysis with a hydroxide.Such copolymers are useful in preventing deposition of scale from water and find applications in treating water. Other applications include scale prevention additives for detergents. In addition, such copolymers inhibit dental tartar and plaque formation.
摘要:
Polymers of maleic acid may be prepared by thermally polymerizing malic acid, maleic acid or fumaric acid with less than one equivalent of ammonia. The polymers are modified by the incorporation of amines, carboxylic acids or combinations thereof. The polymers formed are excellent inhibitors of alkaline earth salt deposition, dispersants, tartar control additives, detergent additives, and water treatment agents.
摘要:
Polymers of maleic, fumaric or malic acids or maleic, fumaric or malic acid and ammonia with amino acids are prepared by heating at 180.degree.-350.degree. C., preferably 200.degree.-300.degree. C. The polymer formed may be converted to a salt by hydrolysis with a metal hydroxide or ammonium hydroxide.
摘要:
This invention discloses methods for manufacture and use of poly(ammonium acrylate) and polyacrylamide hydrogels in agricultural applications. Such hydrogels are applied to the soil or the plants by spraying. Spraying is advantageous over other methods of application, such as mixing with soil and broadcasting because of enhanced plant contact, evenness of distribution, and reduced labor. The gels are prepared for spraying by adding water to provide a readily deformable polymer which will pass through a spray apparatus. The hydrogels sprayed may include additives including micronutrients, maconutrients, pesticides, microbes, plant growth regulators, surfactants, and freezing point modifiers. Use of the hydrogels saves irrigation water and ameliorates salting of irrigated cropland. Sprayed hydrogels may also be used to protect crops from freezing and to protect foliage from desiccation.
摘要:
Methods are disclosed for the preparation of herpesvirus, such as herpes simplex virus type 2 for vaccine use. Such viruses can be grown on serum free or serum containing media and can be prepared from the virus containing culture supernatant or virus containing cells. The virus is prepared for subsequent pharmaceutical formulation by methods which may include treatment with solid phase affinity reagents containing sulfate- or sulfonate-comprising binding groups. Such sulfated polysaccharide groups as heparin or dextran sulfate may be used, and eluted with salt solutions. The process can be combined with other culture, harvesting and formulation steps.
摘要:
A dry zeolite containing composition is used in a method for removing grease and/or oil stains from the human body is disclosed. In accordance with the method, zeolites having an average particle size of about 0.5 mm or less provide superior performance to remove grease and oil stains from the skin. Stain removing activities of the zeolite compositions may be enhanced by the addition of an imide.
