摘要:
The present invention provides a method for functional genomic analysis and antigen prototyping by introducing episomal non-transforming non-viral vector-based cDNA or genomic libraries of donor organisms, pathogens, or cancer cells into host cells. The DNA libraries can be compacted without substantial aggregation to facilitate uptake by host cells. Antigen prototyping can be to identify antigens of pathogens that confer immuno-protection against the pathogens and antigens of cancer cells that confer immuno-protection against the cancer cells..
摘要:
The invention relates to recovering metals, such as nickel and cobalt, by phytomining or phytoextracting soils rich in metals wherein the desired metal is selectively accumulated in hyperaccumulator plants by adjusting the soil pH. The metals are ultimately recovered from above-ground plant tissues at economically acceptable levels without further contaminating the metal-containing sites. The invention also relates to metal-hyperaccumulating plants.
摘要:
This invention relates to a method for controlling the production of cellular (3R)-hydroxyacyl CoA esters of predetermined length in a chosen host cell or organism. In particular, the invention relates to a modified gene encoding a multifunctional 2-enoyl-CoA hydratase 2/(3R)-hydroxyacyl CoA dehydrogenase enzyme type 2 protein and DNA constructs and host comprising the gene. The modification of the gene results in the enrichment of cellular (3R)-hydroxyacyl CoA esters of predetermined length, when the gene is introduced and expressed in a host cell oxidizing exogenous or endogenous null-fatty acids.
摘要:
A method is disclosed for constructing a synthetic polynucleotide from which a protein is selectively expressible in a target cell of a plant, relative to another cell of the plant. The method comprises selecting a first codon of a parent polynucleotide for replacement with a synonymous codon which has a higher translational efficiency in the target cell than in said other cell, and replacing said first codon with said synonymous codon to form said synthetic polynucleotide.
摘要:
Materials and methods for removing metal pollutants from metal-containing substrates, particularly soil environments, using plants modified so as to contain an increased concentration of the amino acid histidine responsible for metal uptake and tolerance.
摘要:
Novel synthetic suppressor tRNA have been provided which provide read-through of internal nonsense mutations, or which can site-specifically alter translation of transcribed sequences. Uses of the same are also provided in genetic engineering protocols including gene therapy treatment of diseases such as Xeroderma pigmentosum.
摘要:
The inventive vector specifically directs entry into a cell of monocytic origin. The vector is composed of a nucleic acid component, a lysosome evading component and a particle that can be phagocytized. The vector itself, or cells pretreated with the vector, are useful in all gene medicine applications. Because it is specific for monocytic cells, the inventive vector is particularly suited to vaccine applications. Due to the ability of monocytic cells to target tumors, the inventive vector also is suitable for use in anti-tumor applications, including conventional gene therapy.
摘要:
This invention relates to the field of biotechnology or genetic engineering. Specifically, this invention relates to the field of gene expression. More specifically, this invention relates to methods to reduce or eliminate transcriptional interference between two or more tandemly arranged genes within a host cell.
摘要:
The invention of this application provides a method comprising introducing a reporter nucleic acid molecule that expresses a fluorescent protein under control of the promoter/enhancer of a gene that is expressed in dopaminergic neurons, into each of cells, and isolating fluorescence-emitting cells. The invention also provides a method for visualizing and identifying dopaminergic neurons alive that exist with in cells, which comprises introducing the above-mentioned reporter nucleic acid molecule into each of cells, and measuring the fluorescence distribution within the cells. The invention further provides a method for identifying a dopaminergic neurons-inducing factor, which comprises introducing the reporter nucleic acid molecule into cells that have the ability to differentiate into dopaminergic neurons, then incubating the cells with a candidate substance, and determining whether the candidate substance is a dopaminergic neurons-inducing factor by using the fluorescence of the cells as an indicator.
摘要:
Different-sequence peptoids, including lipid- and sterol-conjugated peptoids, are found to be effective in transfection of cells with oligonucleotides. Combinatorial libraries of such peptoids can be screened efficiently in a high-throughput format, and selected peptoids are identified post-screening.
