    摘要: Recombinant rabbit tissue factor is cloned and produced in a bacterial host. This protein, which is relatively insoluble and has several disulfide bonds, requires special modifications in order to express and be purified at commercial levels. By expressing the tissue factor as a fusion protein with a bacterial enzyme, thioredoxin, solubility is increased. Use of a thioredoxin reductase deficient host aids in proper tertiary structure for biological activity.

    摘要: A triple host vector is described which is capable of expressing an inserted protein coding DNA sequence in any of three distinct host systems. The vector includes three promoters, one each for vertebrate, bacterial and insect host cells, so that the protein coding sequence can be cloned into the vector once and the vector can be used to express protein in all three types of host cells. The arrangement and selection of the promoters contributes to expression characteristics in all three host systems that is comparable to single host expression vectors.
