GENE EXPRESSION VECTOR CONTAINING HEAT SHOCK PROTEIN GENE HSP83 AND INDUCTIVE GENE EXPRESSION USING SAID VECTOR

摘要

PURPOSE:To make it possible to repeatedly produce a desired physiologically active substance in an amount of strong gene expression, by using a DNA base sequence for controlling heat shock gene expression of Drosophila melanogaster or an inductive sequence as a gene expression controlling DNA base sequence. CONSTITUTION:An extrinsic structural gene is linked to receive transfer control by a DNA base sequence for controlling heat shock gene expression of Drosophila melanogaster having about 83 kilodaltons or an inductive sequence thereof and other factors required for transfer are effectively linked to construct vectors, etc., which are then subjected to heat shock treatment with a transformant cell obtained by eucaryotic cells at a desired time to inductively express the genetic function.
