摘要:
The invention relates to nucleic acids covalently coupled to electrodes via conductive oligomers. More particularly, the invention is directed to the site-selective modification of nucleic acids with electron transfer moieties and electrodes to produce a new class of biomaterials, and to methods of making and using them.
摘要:
The subject invention relates to novel Xenorhabdus toxin complex (TC) proteins and genes that encode these proteins. More specifically, the subject invention relates to TC genes and proteins obtainable from Xenorhabdus bovienii strain ILM104.
摘要:
The invention relates to magnetic resonance imaging agents comprising a paramagnetic metal ion bound to a complex wherein said complex comprises a chelator and a blocking moiety convalently attached to said chelator which binds in at least a first coordination site of said metal ion and which is capable of interacting with a target substance such that the exchange of water in at least said first coordination site is increased.
摘要:
Agrobacterium strains that harbor transformation-enhancing genes on a plasmid capable of replication independently of the Agrobacterium chromosome, the Ti plasmid, and plant transformation binary vectors, and uses for these Agrobacterium strains are provided. Additionally, Agrobacterium strains that are deficient in DNA recombination functions that result in instability or rearrangement of plant transformation binary vectors, and that harbor transformation-enhancing genes on a plasmid capable of replication independently of the Agrobacterium chromosome, the Ti plasmid, and plant transformation binary vectors, and uses for these strains, are also provided. Further included are Agrobacterium strains that harbor transformation-enhancing genes integrated into the Agrobacterium chromosome at a locus that does not interfere with or otherwise compromise the normal growth and plant transformation ability of the Agrobacterium cells, and uses for these Agrobacterium strains. Plants made using these Agrobacterium strains are also described.
摘要:
Compositions for controlling lepidopteran insects use Cry1Fa and Cry1Ab core toxin containing proteins in combination to delay or prevent development of resistance.
摘要:
The present invention relates to magnetic resonance imaging (MRI) contrast agent. In particular, the present invention provides MRI contrast agents that are sensitive to the enzyme beta-glucoronidase. The MRI contrast agents provide compositions and methods for non-invasive diagnostic imaging of tissues, including necrotic tumors.
摘要:
The invention relates to novel methods and compositions for the detection of analytes using the nuclear reorganization energy, λ, of an electron transfer process.
