Abstract:
The present invention provides recombinant host cells that produce proteins or therapeutic proteins, and nucleic acid constructs for producing the cells. The cells have nucleic acid constructs that encode a heterologous protein, for example an antibody. The nucleic acid constructs also can have a functional signal sequence that directs the secretion of the protein from the cell. The signal sequence can be any functional signal sequence, and various signal sequences are disclosed herein. The invention also provides methods of producing the proteins.
Abstract:
Recombinant microorganisms engineered for the production of polyunsaturated fatty acids (PUFAs) are provided. Also provided are biomass, microbial oils, and food products and ingredients produced by or comprising the microorganisms of the invention.
Abstract:
The present application provides novel regulatory elements including promoter sequences from marine microorganisms. The application further discloses DNA constructs containing these novel regulatory elements; transgenic cells, transgenic non-human organisms, and progeny containing these novel regulatory elements. Methods of modifying, producing, and using the regulatory elements are also disclosed. The regulatory elements disclosed herein are particularly suited for use in Nannochloropsis and other microalgae.
Abstract:
The present invention discloses methods for assembling a nucleic acid molecule from a set of overlapping oligonucleotides. The method involves contacting a set of overlapping oligonucleotides with a DNA polymerase, a mixture of dNTPs, and a crowding agent to form an assembly mixture. In one embodiment the crowding agent is polyethylene glycol (PEG). The presence of the crowding agent facilitates the nucleic acid assembly process of the invention. The assembly mixture is then subjected to multiple cycles, each cycle comprising an annealing phase, an extension phase, and a denaturation phase, and the desired nucleic acid molecule is thereby assembled. In some embodiments one or more of the phases are time varied.
Abstract:
The present disclosure generally relates to novel polynucleotide molecules for use in regulating gene expression in recombinant cells, such as labyrinthulomycetes cells. The disclosure further relates to nucleic acid constructs, such as vectors and expression cassettes, containing a regulatory element operably linked to a heterologous nucleotide sequence. The disclosure further relates to methods for stably transforming a host cell, such as a labyrinthulomycetes cell with transgenes. Stably transformed recombinant cells, progeny, biomaterials derived therefrom, and methods for preparing and using the same are also provided.
