摘要:
The present invention discloses a polynucleotide sequence for an insect salivary glucose oxidase enzyme and the amino acid sequence of the enzyme itself. It also provides recombinant polynucleotide vector systems designed to express the enzyme in a variety of host organisms. The invention also discloses a method for creating transgenic plants having increased resistance to insect predation resulting from the expression of the foreign glucose oxidase protein. The presence of the insect glucose oxidase enzyme triggers a plant's defensive mechanisms and results in increased resistance to insects.

The invention provides improved methods of introducing site-directed mutations into circular DNA molecules of interest by means of mutagenic primer pairs. The mutagenic primer pairs are also selected so as to be either completely complementary or partially complementary to each other, wherein the mutation site (or sites) is located within the region of complementarity. A mutagenic primer pair is annealed to opposite strands of a circular DNA molecule containing the DNA sequence to be mutagenized. After annealing, first and second mutagenized DNA strands, each incorporating a member of the mutagenic oligonucleotide primer pair is synthesized by a linear cyclic amplification reaction. After the linear cyclic amplification mediated synthesis step is completed, the reaction mixture is treated with a selection enzyme that digests the parental template strands. After the digesting step, a double-stranded circular DNA intermediate is formed. The double-stranded circular DNA intermediates is transformed in suitable competent host cells and closed circular double-stranded DNA corresponding to the parental template molecules, but containing the desired mutation or mutations of interest, may be conveniently recovered from the transformed cells. The invention also provide kits for site-directed mutagenesis in accordance with methods of the present invention.

Abstract of DisclosureThe present invention is directed generally to reduction or inactivation of gene function or gene expression in cells in vitro and in multiorganisms. The invention encompasses methods for mutating cells using a combination of mutagens, particularly wherein at least one mutagen is an insertional mutagen, to achieve homozygous gene mutation or mutation of multiple genes required cumulatively to achieve a phenotype to create knock-outs, knock-downs, and other modifications in the same cell. The invention is also directed to cells (and libraries thereof) and organisms created by the methods of the invention, including those in which at least one of the genes created by insertional mutagenesis is tagged by means of the insertion sequences thereby allowing identification of the mutated gene(s). The invention is also directed to libraries of mutated cells and their uses. The invention is also directed to methods of identifying mutations with methods of the invention, in cells (and libraries thereof) and organisms, by means of the insertional tag.

Methods and kits for detecting kinase activity A method for measuring protein kinase activity comprising: (a) providing a first solution comprising ATP and a protein kinase to be tested, and a second solution comprising ATP in the absence of said kinase to be tested; (b) adding a substrate capable of being phosphorylated by the protein kinase to be tested to the first and second solutions of step (a); (c) measuring the concentration of ATP and/or ADP, or the rate of change thereof with respect to time, in each of the reaction mixtures formed in step (b) using a bioluminescence reaction; and (d) using the information about the concentration of ATP and/or ADP to determine the activity of the protein kinase to be tested.
摘要:
A method for quantitating cellular proteins in tissue, by means of a cell imaging densitometer in conjunction with immunohistological staining and a reference standard, is provided. Unlike prior art methods, which provide ordinal measures of relative amounts of protein among different cells, the method enables the quantitation of antigenic proteins in terms of absolute mass of protein/tumor or protein/patient, molecules of protein per cell, and volume or fraction of a tissue sample expressing the protein of interest. The method is useful for research purposes in the study of protein expression, and is shown to improve the accuracy of clinical histopathological analysis of tumor tissue sections for diagnosis and prognosis. The method is expected to be useful for prescribing in situ treatment dosages. The demonstrated resulting improvement in the correlation between tissue levels and blood levels of tumor-associated proteins should facilitate minimally-invasive monitoring of cancer progression and therapeutic response.
