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.

An antibody of a human leukemia virus-related peptide obtained by collecting an antibody produced in a mammal body by administering to the mammal an antigen prepared by reacting a human leukemia virus-related peptide selected from the group consisting of:(a) a peptide represented by formula (1):H-Tyr-Val-Glu-Pro-Thr-Ala-Pro-Gln-Val-Leu-H (1)(b) a peptide represented by formula (2): psR-Ile-Pro-His-Pro-Lys-Asn-Ser-Ile-Gly-Gly-Glu-Val-OH (2)wherein R is the same as defined above;(c) a peptide represented by formula (3):R-Thr-Trp-Thr-Pro-Lys-Asp-Lys-Thr-Lys-Val-Leu-OH (3)wherein R is the same as defined above;(d) a peptide represented by formula (4):H-Val-Val-Gln-Pro-Lys-Lys-Pro-Pro-Pro-Tyr-OH (4)(e) a peptide represented by formula (5):R-Met-Gly-Gln-Ile-Phe-Ser-Arg-Ser-Ala-Ser-Pro-OH (5)wherein R is the same as defined above; and(f) a peptide represented by formula (6):H-Tyr-Pro-Glu-Gly-Thr-Pro-Lys-Asp-Pro-Ile-Leu-Arg-Ser-Leu-OH (6)as a hapten, with a carrier in the presence of a haptencarrier binding agent.
摘要:
A viral genomic DNA and fragments thereof which are complementary to genomic RNA of human leukemia virus and a recombinant DNA molecules containing the genomic DNA or fragments thereof. The genomic DNA and fragments thereof and the recombinant DNA molecules are useful for the diagnosis, prevention and therapy of human leukemia.
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:
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:
Monoclonal antibodies are disclosed that may be produced by hybridomas obtained by fusing a mouse spleen cell immunized with an ADRIAMYCIN.RTM.-resistant human tumor cell and a mouse myeloma cell and which inhibit selectively the growth of cancer cells possessing pleiotropic drug resistance or enhance their sensitivity to said drug.
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.
