  • Patent number: 6830887
    Abstract: Quantitative and qualitative analysis of a nucleic acid analyte in a sample suspected to contain the nucleic acid analyte if achieved by first preparing a reaction mixture containing the sample and a known amount of an internal quantitation standard. At least a first aliquot of the reaction mixture is combined with a set of amplification reagents effective to amplify nucleic acids in the reaction mixture. The set of reagents includes at least one primer pair which is effective to amplify a first region of the nucleic acid analyte if present in the sample to produce a first amplified sample fragment and to amplify at least a portion of the internal quantitation standard to produce a control fragment. Amplification results in the formation of an amplification product mixture containing first amplified sample fragments and control fragments when the nucleic acid analyte is present in the sample, and only control fragments when the nucleic acid analyte is not present in the sample.

  • Patent number: 6830904
    Abstract: Methods for producing single diastereomers of isoleucine in high stereochemical purity are provided. D-isoleucine is produced by converting (R)-2-methylbutyraldehyde to a diastereomeric mixture of D-isoleucine hydantoin and L-allo-isoleucine hydantoin (5S-[(R)-1-methylpropyl]hydantoin) under conditions whereby no significant racemization of the chiral center in (R)-2-methylbutyraldehyde occurs, followed by contacting said diastereomeric hydantoin mixture with a D-hydantoinase to stereoselectively hydrolyze any D-isoleucine hydantoin in the mixture to the corresponding N-carbamoyl-D-isoleucine, preferably under conditions permitting the simultaneous epimerization of the chiral center at C-5 of the hydantoin. The simultaneous epimerization permits the reaction to be carried out to substantial completion so that the diastereomeric hydantoin mixture is converted to N-carbamoyl-D-isoleucine in high yield. The N-carbamoyl-D-isoleucine is then decarbamoylated to produce D-isoleucine.

  • Patent number: 6830910
    Abstract: The invention encompasses Drosophila Recombination Associated Protein (DRAP) isolated D. melanogaster and a nucleic acid sequence encoding DRAP. The Drosophila Recombination Associated Protein, its homologues from other organisms or active peptides derived therefrom, as well as DNA encoding such protein are useful for homology-dependent pairing of three DNA strands. The combination of strand-transfer and topoisomerase activities associated with DRAP permits directed pairing and cleavage at defined site(s) within DNA. This in turn makes possible the isolation and/or removal of a defined segment of DNA. DRAP is also useful in cloning, genomic cloning and gene mapping, in promoting gene disruptions or “knockout” mutations, in carrying out targeted mutagenesis of specific genes and in generating transgenic animals.

  • Patent number: 6830925
    Abstract: Methods for isolating CaMK-X1 genes are provided. The CaMK-X1nucleic acid compositions find use in identifying homologous or related proteins and the DNA sequences encoding such proteins; in producing compositions that modulate the expression or function of the protein; and in studying associated physiological pathways. In addition, modulation of the gene activity in vivo is used for prophylactic and therapeutic purposes, such as identification of cell type based on expression, and the like.

  • Patent number: 6830926
    Abstract: The present invention provides a method for evaluating the ability of a compound to inhibit protoporphyrinogen oxidase activity, which comprises the steps of (1) culturing a transformant expressing a heterologous protoporphyrinogen oxidase (PPO) gene in a medium containing substantially no protoheme compounds in the presence and absence of a test compound to measure the growth rate of the transformant, wherein the transformant is a host cell deficient in PPO activity which is transformed with the heterologous PPO gene, and (2) determining the ability of the compound to inhibit the protoporphyrinogen oxidase activity by comparing growth rates.

  • Patent number: 6830927
    Abstract: A method of generating neural crest stem cells involves inducing neuroepithelial stem cells to differentiate in vitro into neural crest stem cells. Differentiation can be induced by replating the cells on laminin, withdrawing mitogens, or adding dorsalizing agents to the growth medium. Derivatives of the peripheral nervous system can be generated by inducing the neural crest stem cells to differentiate in vitro.

  • Patent number: 6830929
    Abstract: The invention relates to constructs capable of infecting mammalian cells comprising at least one semi-purified or pure SV40 capsid protein and a constituent selected from the group consisting of an exogenous DNA, a vector comprising an exogenous DNA, an exogenous RNA, a vector comprising an exogenous RNA, an exogenous protein or peptide product, and antisense RNA, ribozyme RNA or any RNA or DNA which inhibits or prevents the expression of undesired protein(s) in the mammalian cell and optionally further comprising operatively linked regulatory elements sufficient for the expression and/or replication of the exogenous protein in a mammalian cell. The invention further relates to a method for the in vitro construction of SV40 virus or pseudovirus constructs according to the invention.

  • Patent number: 6830930
    Abstract: The GAI gene of Arabidopsis thaliana has been cloned, along with mutant and homologue gene sequences. Expression of such genes a plants affects characteristics in the plants including growth. GAI expression inhibits growth of plants, which inhibition is antagonized by gibberellin (GA). Expression of gai mutants confers a dwarf phenotype which is GA-insensitive. Manipulation of expression of GAI and gai genes in plants results in tall or dwarfed plants. Dwarf plants are useful in particular for reduction in crop losses resulting from lodging.

  • Patent number: 6830934
    Abstract: A medical diagnostic device has a non-absorbent substrate that has a hydrophilic target area on which a reagent is deposited by non-impact printing of microdroplets. During deposition, the device is moved relative to the stream of microdroplets to form a substantially uniform reagent layer on the substrate. The device is particularly well adapted for measuring blood coagulation times. In a preferred embodiment, coagulation times are determined by monitoring the optical transmission of light through the target area as an applied blood sample interacts with the reagent.
