摘要:
Disclosed are recombinant vector plasmids containing a DNA fragment coding for human interferon-β inserted downstream from a tryptophane promoter. The plasmids are useful for transformation of microorganisms such as Escherichia coli which transformants produce human interferon-β.

摘要:
According to the present invention, a recombinant DNA wherein a DNA coding for a novel physiologically active polypeptide produced by human erythroleukemia cell strain K562-T1 is incorporated and a microorganism or an animal cell carrying the recombinant DNA can be obtained, and they can be utilized for producing a large amount of the physiologically active polypeptide.
摘要:
Disclosed is a process for expressing a gene and producing a metabolic product formed by the gene by culturing a transformant microorganism carrying a recombinant DNA constructed of a DNA fragment having at least one gene to be expressed and a vector DNA, at least one of which is foreign to the host microorganism.
