摘要:
The present invention relates to human interferon-.beta. gene derived from human chromosome, a DNA containing said gene and a DNA responsible for control of its transcription and a recombinant DNA of said DNA and a vector DNA. The gene and DNA of the present invention are introduced in eukaryotic cells and used for the production of human interferon-.beta..
摘要:
Disclosed is a recombinant plasmid having a gene which encompasses at least the entire coding region of human fibroblast interferon messenger RNA and a method for preparing such plasmid.
摘要:
A gene coded for a polypeptide which possesses interleukin-2 is isolated, and connected with a vector DNA which is capable of replicating in a procaryotic or eucaryotic cell at a position downstream of a promoter gene in the vector obtaining a recombinant DNA, with which the cell is trans-formed to produce interleukin-2.

摘要:
A gene coded for a polypeptide which possesses interleukin-2 activity is isolated, and connected with a vector DNA which is capable of replicating in a procaryotic or eucaryotic cell at a position downstream of a promoter gene in the vector obtaining a recombinant DNA, with which the cell is transformed to produce interleukin-2.
摘要:
Recombinantly produced interleukin-2 exhibits human IL-2 activity, has a molecular weight of about 15,000 daltons, is activity stable at a pH of 2-9 and is resistant to elevated temperatures. The recombinant IL-2 has the principal biological activity of human IL-2, promotion of proliferation of cytotoxic T lymphocytes.

摘要:
Disclosed is a novel DNA which shows complementarity to human interferon-.gamma. mRNA, a recombinant plasmid containing the DNA, a microorganism containing the recombinant plasmid and a method of producing the same as well as a process for producing a polypeptide having human interferon.gamma. activity using the microorganism.
摘要:
Recombinant plasmids are constructed by inserting a DNA fragment coding for a fused protein of an adult T cell leukemia virus antigen peptide and an enzyme into a vector DNA. Microorganisms are transformed with the recombinant plasmid and thereafter cultured to express the fused protein. The fused protein is useful for the detection and diagnosis of adult T cell leukemia.
摘要:
Recombinant human Interleukin-2 (IL-2) polypeptides are provided. The polypeptides are produced by expression of suitable nucleic acid molecules in transformed host cells such as E. coli.
