摘要:
The present invention has for its object to provide novel biologically active substances which is of value as a therapeutic agent for fungal infections and immune disorders. This invention is related to a biologically active substance TKR2449 analog(s) which is represented by the following general formula (A); (In the formula, R 1 , R 2 and R 3 are the same or differ each other, and each represents hydrogen or an alkyl group of carbon number of 1 to 4. R 4 is a linear or branched alkyl or alkenyl group of carbon number of 1 to 8.).
摘要:
Germ cells having a desired foreign gene integrated thereinto; a convenient method for acquiring a vertebrate carrying these cells; and a method for constructing a novel vertebrate line by using these cells and the vertebrate. Namely, a method for transferring a foreign gene into the testes of a vertebrate which involves the step of decreasing a testicular cell number and the step of inoculating a recombinant virus carrying the foreign gene into the testes; the vertebrate having the foreign gene transferred thereinto by the above method; testicular cells obtained from the vertebrate and having the foreign gene transferred thereinto; a vertebrate obtained by mating the above vertebrate and carrying the transferred foreign gene; and a vertebrate obtained by artificial fertilization with the use of the testicular cells and carrying the transferred foreign gene; and a vertebrate obtained by artificial fertilization with the use of the testicular cells and carrying the transferred foreign gene.
摘要:
Gene therapeutics to be used in treating diseases showing sensitivity to gene therapy, characterized by containing as the active ingredient an efficacious amount of a functional substance which has a function of having an affinity for a virus containing a gene usable in the gene therapy and another function of having an affinity specific for a target cell with a need for the gene transfer, or an efficacious amount of a functional substance which has an affinity for the above virus and an efficacious amount of another functional substance which has an affinity specific for the above cell.
摘要:
Improved methods for transferring a gene into target cells by using a retrovirus, wherein the gene transfer efficiency is improved and the target cells are efficiently transformed by binding the retrovirus to a functional substance which is immobilized on as carrier and having an activity of binding to retroviruses followed by washing; using an antibody capable of specifically recognizing cells, laminin or mannose-rich type sugar chain as a substance having an activity of binding to the target cells; pre-treating the target cells so as to inactivate transferrin receptor, or introducing a new functional group into the functional substance.

摘要:
A method of transferring a foreign gene into cells, characterized by involving: the step of transferring into the cells with the use of an adenovirus vector, a first nucleic acid, which has a sequence provided with adeno-associated virus-origin ITRs in both sides of the target foreign gene to be transferred, and a second nucleic acid, which has an adeno-associated virus-origin rep gene and a promoter for expressing this gene and carries a stuffer sequence inserted thereinto sandwiched in two recombinase recognition sequences and located between the rep gene and the promoter; and the step of expressing the Rep protein under the action of recombinase in the cells obtained in the above step to thereby integrate the target foreign gene into the chromosomal DNA.
