FIELD: pharmacology.
SUBSTANCE: method for antibody production, a method for production of a pharmaceutical preparation containing an antibody obtained by this method, a nucleic acid molecule, application of a vector containing such nucleic acid molecule, and application of a cell where the said nucleic acid molecule or vector is artificially introduced in the method for antibody production. This method for antibody production involves culturing a cell that expresses an antibody-enhancing sequence (APES) that has been artificially inserted into a cell and into which an exogenous DNA encoding the desired antibody was introduced to produce the desired antibody, and wherein APES is a nucleic acid molecule containing a nucleotide sequence that can bind to DNA or mRNA of NfkBia gene derived from a human, mouse, rat, or hamster by base pairing, and can suppress expression of the NfkBia gene.
EFFECT: invention allows production of an antibody at a high level with suppression of NfkBia expression.
