摘要:
The present invention provides peptides libraries which are useful for rapid identification of biologically active compounds. The invention further provides peptides which include cell-growth affecting peptides and peptides which enhance or inhibit production of cellular proteins. Many of the peptides of the invention may be produced in large quantity by recombinant techniques and formulated in culture medium to produce the desired effect on cultured cells and tissues. Certain of the libraries of the invention and the peptides identified in them are particularly useful in concatemer-based recombinant expression methods.
摘要:
A method for identifying and sorting variants of a chosen enzyme is disclosed. Enzyme variants of a chosen enzyme are obtained and then linked to their corresponding genetic code through any of a family of suitable surface display methods. The enzyme variants, now displayed on the surface of a biological particle such as a phage, virus, yeast, or bacterium are then encapsulated in a vesicle containing an enzyme activity-sensitive assay reagent. The enzyme variant is thus exposed to the assay reagent, and displays a signal using the enzyme activity-sensitive assay reagent in a manner proportionate to the levels of activity of the enzyme, thus rendering the vesicles suitable for mechanical sorting based on these levels. The vesicles are then sorted using methods known in the art to isolate those variants exhibiting possibly beneficial variations in enzyme function.

The invention relates to compositions, kits, and methods for detecting, characterizing, preventing, and treating human prostate cancers. A variety of novel markers are provided, wherein changes in the levels of expression of one or more of the markers is correlated with the presence of prostate cancer.
摘要:
The present invention relates to a composition comprising a plurality of cDNAs which are differentially expressed in prostate cancer and which may be used in their entirety or in part as to diagnose, to stage to treat or to monitor the treatment of a subject with prostate cancer.
摘要:
The present invention relates to technology for constructing a reaction system including a test target, an oxidation-reduction enzyme, and an electron mediator, and measuring the concentration of the test target by an electrochemical process. A Ru compound is used as the electron mediator. The present invention provides a concentration test instrument including a substrate, first and second electrodes formed on the substrate, and a reagent layer formed as a solid. The reagent layer contains an oxidation-reduction enzyme and a Ru compound, and is constituted so as to dissolve and construct a liquid phase reaction system when a sample liquid is supplied.

摘要:
The invention relates to a novel enzyme obtained from Bacillus agaradherens (DSM 9948), which can be regarded as cyclodextrin glucanotransferase (CGTase) and also as null-amylase. The invention also relates to sufficiently similar proteins or derivatives that exhibit amylolytic and/or CGTase activity, to the corresponding nucleic acids and micro-organisms that produce said proteins and derivatives, to methods for the production of said proteins and to diverse uses of the same. In addition, said proteins can be further developed for other, predominantly technical purposes. The invention relates in particular to detergents and cleaning agents containing CGTase of this type, to methods for cleaning textiles or hard surfaces using CGTase of this type or corresponding agents and to the use thereof for cleaning textiles or hard surfaces.

摘要:
Disclosed is a method for producing protein preparations having essentially constant functional properties for technical applications within a broad pH range from about pH 3 to pH 10 by means of extraction from a starting product which contains protein, notably legumes, grains or oilseed. The invention is distinguished by the protein-containing starting product undergoing at least one liquid extraction step and that the raffinate and/or extract obtained thereby undergoes at least one membrane separation process in which a residue is obtained or undergoes thermal upgrading in which a concentrate is obtained and that the residue or the concentrate contain the protein preparations having the desired functional properties.
