摘要:
Disclosed is a method for producing a cell population containing memory-like T cells, said method being characterized by including a step for in vitro culturing of a cell population containing T cells or T cell precursor cells using a retinoic acid and a CD3 ligand. Further disclosed is a method for producing a cell population wherein the proportion of memory-like T cells is increased and wherein a desired gene is introduced with a high efficiency and is highly expressed.
摘要:
Provided are a production method for non-enveloped virus particles which is characterized in that a sample including non-envelopes virus particles is treated with PEG in at least two concentrations; a kit used in said production method; non-enveloped virus particles produced using said production method; and a pharmaceutical composition having the non-envelopes virus particles as an active ingredient.
摘要:
The present invention provides a method for producing a virus vector, which involves a step of culturing a cell capable of producing the virus vector in a culture medium containing a retinoic acid compound, a histone deacetylase-inhibiting substance and a substance capable of forming a chelate; and a culture medium for use in the production of a virus vector, which is characterized by containing a retinoic acid compound, a histone deacetylase-inhibiting substance and a substance capable of forming a chelate as active ingredients.
摘要:
A hyperthermostable protease having the amino acid sequence represented by the SEC ID NO:1 of the Sequence Listing or a sequence derived therefrom by deletion, substitution, insertion or addition of one to several amino acid residues, a gene encoding the hyperthermostable protease, and a process for preparing the protease, aiming at providing by genetic engineering techniques a hyperthermophile protease which is advantageous for industrial use.
摘要:
The present invention provides a method for efficiently manufacturing a non-enveloped virus with high purity without laborious operation by cultivating cells having the ability to produce a non-enveloped virus and bringing the cells and an acidic solution into contact with each other. A non-enveloped virus vector manufactured by the method of the present invention and a composition having the non-enveloped viral vector as an active ingredient are very useful as gene transfer methods in the fields of basic research and clinical application gene therapy.
