Process for purifying spergualin-related compounds and their synthetic intermediates, by subjecting a solution containing such spergualin-related compounds or intermediates to electrodialysis and/or reverse osmosis.
摘要:
A nucleic acid comprising a transcription regulation sequence whose transcription is induced by a trans-acting factor of a human immunodeficiency virus and a gene encoding a polypeptide having an endoribonuclease activity specific to single-stranded RNA, wherein the gene is located in such a position that the expression of the gene can be regulated by the transcription regulation sequence; a method for production of a cell showing an inhibited replication of a human immunodeficiency virus therein, the method comprising the step of introducing the nucleic acid into a cell; and a method for treatment or prevention of a human immunodeficiency virus infection.
摘要:
A DNA synthesis reaction-enhancer comprising at least one kind selected from the group consisting of acidic substances and cationic complexes; a DNA synthesis method in which during a DNA synthesis reaction a reaction is carried out in the presence of the above enhancer by using DNA polymerase; a DNA synthesis reaction composition comprising the above enhancer; a DNA synthesis reaction composition comprising two or more kinds of DNA polymerases each having 3′→5′ exonuclease activity; a DNA synthesis method in which during a DNA synthesis reaction two or more kinds of DNA polymerases each having 3′→5′ exonuclease activity are used; a kit for use in in vitro DNA synthesis, comprising two or more kinds of DNA polymerases each having 3′→5′ exonuclease activity; and a kit for use in in vitro DNA synthesis, wherein the kit comprises the DNA synthesis reaction-enhancer and DNA polymerase. According to the present invention, DNA synthesis can be carried out at an efficiency more excellent as compared to conventional DNA synthesis reaction.
摘要:
Disclosed is a method for enhancing the function of a T cell, which is characterized by inhibiting the expression of programmed death-1 ligand 1 (PD-L1) and/or programmed death-1 ligand 2 (PD-L2) in the T cell. Also disclosed is a function-enhanced T cell which is produced by the function enhancement method. Further disclosed is a therapeutic agent comprising the function-enhanced T cell. The T cell can enhance an immune response to cancer, and is useful in an immunotherapy effective for cancer and the treatment or prevention of infectious diseases and autoimmune diseases.

摘要:
A polymerase activity is effectively enhanced by adding an anionic surfactant, in particular an anionic surfactant having a polyethoxyl group, to a reaction mixture containing a polymerase.
摘要:
A process for producing an extract containing activated osteocalcin; an extract which can be obtained by this production process; a food, a drink, a drug, an oral cavity-care composition and a feed containing this extract; and a growth enhancer containing osteocalcin originating in a bone.
摘要:
To find a substance which has a skin cosmeticizing effect such as prevention of skin aging, amelioriation of sensitive skin, or antipruritic action, and can serve as an effective ingredient for a hair-care product, thereby providing cosmetics comprising the effective ingredient. Concretely, there are provided cosmetics characterized in that the cosmetics comprise as an effective ingredient a compound selected from a fucoidan, a degradation product thereof, a sulfated monosaccharide or a salt thereof.
