摘要:
The present invention provides a modified nucleic acid for expressing bovine lactoferricin (LFB) in algae, which consists of SEQ ID NO: 3. The present invention also provides a method of producing a foreign desired gene product in algae, comprising: (a) weakening or removing cell wall of the algae by a protein enzyme solution to make algae become suitable for gene transfer; (b) transferring a foreign gene encoding the desired gene product into the algae; and (c) expressing the foreign gene to produce the desired gene product. The present invention further provides a feed composition comprising a transgenic algae or its offspring, wherein the cell wall of said transgenic algae is weakened or removed by a protein enzyme solution.

摘要:
A method of expressing in vivo heart-specific fluorescence in transgenic line of zebrafish is developed, which provides a research model for studying heart-related gene functions and performing gene therapies in the future. The method comprises the following steps. Firstly, a plasmid is constructed. This plasmid construct includes the upstream regulatory region, the exon 1, the intron 1, and the exon 2 of cmlc2 gene, cDNA of GFP, wherein the cmlc2 gene and GFP cDNA form a cassette, and inverted terminal repeats from adeno-associated virus are flanked at both sides of this cassette. The plasmid construct is linearized and microinjected into one-celled zebrafish fertilized eggs. Lastly, the heart-specific fluorescent expressed zebrafish are selected and the germline-transmitting transgenic strain is generated.

摘要:
Recombinant plasmids comprising (a) a ubiquitous promoter, (b) one fluorescent gene, the gene being operably liked to and inserted downstream of the ubiquitous promoter, (c) a skin-specific or muscle-specific promoter, and (d) another fluorescent gene, the gene being operably linked to and inserted downstream the skin-specific or muscle specific promoter. The ubiquitous promoter and the skin-specific or muscle promoter have the adverse directional property and the ubiquitous promoter and the skin-specific or muscle-specific promoter are located upstream of the fluorescent gene and the another fluorescent gene respectively so as to have the directional property which permits transcription of the genes. Host cells, transgenic fish harboring the plasmid of the invention and methods of producing a transgenic fish can be made with the plasmids of the invention.
