摘要:
Provided is a method for producing non-enveloped viral particles, comprising a step for obtaining a fraction containing non-enveloped viral particles by removing precipitates which are produced in a step for adding a substance which reduces the solubility of proteins under acidic conditions and/or a substance which precipitates under acidic conditions to a neutral or basic sample containing non-enveloped viral particles, and acidifying the sample after the addition of the substance.
摘要:
The present invention pertains to: (1) an expression control region which has a sequence corresponding to a transcriptional activator binding domain; and (2) a nucleic acid which codes a transcriptional activator capable of binding to the expression control region. Provided are: an expression cassette including the nucleic acid connected to the expression control region in a manner so as to be capable of functioning; a method for expression of a product of interest in mammalian cells, said method using the expression cassette; a method for production of cells which express the product of interest; a method for production of the product of interest in mammalian cells; and a kit which includes the expression cassette.
摘要:
A method for quantification of an adeno-associated virus genome, including the steps of (a) preparing a composition containing a sample, at least one primer pair for use in amplification of only a nucleotide sequence contained in inverted terminal repeats of an adeno-associated virus, and an intercalating dye; (b) performing nucleic acid amplification reaction using the composition prepared in the step (a); and (c) detecting an amplified product obtained in the step (b). The present invention is especially useful in the fields of medicine, gene engineering, and biology.
