    摘要: The present invention provides compounds and compositions capable of stimulating plant growth, regeneration of plant cells and tissues, and transformation of plant cells and tissues, comprising mono- and multi-substituted auxinic analogues of indole-3-acetic acid (IAA) comprising substituent groups such as halo-, alkyl-, alkoxy-, acyl-, acylamido- and acyloxy-groups. The invention relates to a method of using such mono- and multi-substituted auxinic analogues of IAA to affect growth, regeneration or transformation in monocotyledonous and dicotyledonous plants, as well as in transgenic plant tissues. The invention also contemplates the use of these auxinic IAA analogues in the presence of other plant growth regulators, such as cytokinin, etc., to enhance plant growth.

    摘要: The present invention relates generally to nutritive medium, medi0m supplement, media subgroup and buffer formulations. Specifically, the present invention provides powder nutritive medium, medium supplement and medium subgroup formulations, particularly cell culture medium supplements (including powdered sera such as powdered fetal bovine serum (FBS)), medium subgroup formulations and cell culture media comprising all of the necessary nutritive factors that facilitate the in vitro cultivation of cells. The invention further provides powder buffer formulations that produce particular ionic and pH conditions upon reconstitution with a solvent. The invention is particularly directed to methods of production of these media, media supplement, media subgroup and buffer formulations, and also provides kits and methods for cultivation of prokaryotic and eukaryotic cells, particularly bacterial cells, yeast cells, plant cells and animal cells (including human cells) using these dry powder nutritive media, media supplement, media subgroup and buffer formulations. The invention also relates to methods of producing sterile powdered media, media supplement (particularly powdered sera such as powdered FBS, powdered transferrin, powdered insulin, powdered organ extracts (such as bovine brain or pituitary extracts), powdered growth factors (such as EGF, FGF, etc.) and the like), media subgroup and buffer formulations. In a particularly preferred aspect, the invention relates to such methods wherein the sterilization is accomplished by gamma irradiation. The invention also relates to methods for producing dry cell powders, comprising spray-drying a cell suspension. The invention also relates to cell, media, media supplement, media subgroup and buffer powders produced by these methods.

    摘要: The present invention relates to a DNA and RNA polymerases which have increased fidelity (or reduced misincorporation rate). In particular, the invention relates to a method of making such polymerases by modifying or mutating the nucleotide binding domain of the polymerase (e.g., the O-helix). The invention also relates to DNA molecules containing the genes encoding the polymerases of the invention, to host cells containing such DNA molecules and to methods to make the polymerases using the host cells. The polymerases are particularly suited for nucleic acid synthesis, sequencing, amplification and cDNA synthesis.

    摘要: Binding of eIF-4E to the 5'm7G cap structure of eukaryotic mRNA signals the initiation of protein synthesis. In the present invention, the binding site cap-binding domain of eIF-4E was identified as the region containing the sequence Trp?113 to Arg122¿. Thus, in a first preferred embodiment the present invention provides a truncated peptide of the cap binding protein consisting essentially of the mRNA cap-binding domain. Specifically, the invention concerns eIF-4E cap binding peptide and its variants. In additional preferred embodiments, the invention provides an isolated nucleic acid molecule which encodes a truncated peptide of the eIF-4E protein consisting essentially of the mRNA cap-binding domain of eIF-4E; a recombinant vector and host cell comprising the above-described nucleic acid molecule; and a recombinant peptide produced thereby. The invention further provides the truncated or recombinant peptides immobilized on a solid support, a resin comprising the truncated or recombinant peptides immobilized on a solid support, methods and kits for isolating a capped mRNA molecule, and methods and kits for producing a full-length cDNA molecule.

    摘要: This invention is directed to compositions comprising mixtures of reagents, including thermostable enzymes (e.g., thermostable DNA polymerases), buffers, cofactors and other components, suitable for immediate use in nucleic acid amplification or sequencing techniques without dilution or addition of further components. The compositions contain no stabilizing agents (e.g., glycerol or serum albumin) and unexpectedly maintain activity for extended periods of time upon storage at temperature above freezing. These compositions are useful, alone or in the form of kits, for nucleic acid amplification (e.g., by the Polymerase Chain Reaction, as exemplified in the Figure) and sequencing (e.g., by dideoxy or 'Sanger' sequencing), or for any procedure utilizing thermostable DNA polymerases in a variety of medical, forensic and agricultural applications. In particular, the compositions and methods are useful for amplifying and sequencing nucleic acid molecules that are larger than about 7 kilobases in size.
