摘要:
Cyclopentenone derivative having a structure of 5-(R.sub.1 COO--)-4-(R.sub.2 COO--)--substituted 2-cyclopenten-1-one (R.sub.1 and R.sub.2 are some or different and each is alkyl group, alkenyl group or aryl group) or an optically active substance thereof; a method for the manufacture of the cyclopentenone derivative by the reaction of 4,5-dihydroxy-2-cyclopenten-1-one with the corresponding carboxylic acid or a reactive derivative thereof; and anticancer agent, apoptosis-inducing agent and antibacterial agent containing said derivative.
摘要:
An isolated hyperthermostable .beta.-galactosidase gene derived from Pyrococcus furiosus is described. Examples include DNA sequences shown in SEQ ID NO. 2 and SEQ ID NO. 4 and DNAs hybridizable with these DNAs. A method of cloning the hyperthermostable .beta.-galactosidase gene in which each of the above sequences or portions thereof is used as a probe or primer is described. A process for producing a hyperthermostable .beta.-galactosidase by culturing a transformant into which a plasmid containing each of the above genes has been introduced is described. A particularly preferred gene encodes an SDS-resistant hyperthermostable .beta.-galactosidase.

摘要:
The present invention provides a method for increasing the efficiency of gene transfer into target cells with a retrovirus. The transduction is affected by infecting target cells with a retrovirus in the presence of a mixture of a functional material having a retrovirus binding domain, and a second functional material having target cell binding domain. The target cells may be selected from the group of unintentional hematopoietic progenitor cells and erythrocyte precursor, specifically pluripotent stem cells or embryopalstic stem cells.

摘要:
The N-acetylglucosaminyltransferase III activity is enhanced in a cell carrying retrovirus-origin gag-pol gene and env gene. By constructing a retrovirus vector with the use of the above cell, a retrovirus vector having a modified sugar chain structure can be obtained. The retrovirus vector constructed by this method shows a high infection efficiency particularly in the presence of a functional substance.
摘要:
The present invention provides a kit to carry out retrovirus-mediated gene transfer into target cells. The kit contains a functional material bearing a retrovirus binding domain, another functional material bearing a target cell binding domain, an artificial substrate for incubating the retrovirus contacted with the target cells, and a target cell growth factor for pre-stimulating target cells to spur them along the cell cycle. The kit of the invention may further comprise a recombinant retroviral vector, necessary buffers, and the like.
