摘要:
Interleukin-2 polypeptides, which are free from substances produced by human cells, are provided. These interleukin-2 polypeptides are produced by a culture of cells of Escherichia coli, constructed by gene-recombination technique, into which a plasmid comprising the genetic information for the synthesis of human IL-2, has been inserted.
摘要:
@ There is disolved a cell of Saccharomyces cerevisiae transformed with a recontinant DNA comprising a gene coding for a polypeptide possessing the activity of interieukin-2 and a vector DNA capable of propagating in said cell, the coding sequence of said gene being located at a position downstream of a promoter sequence.
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:
Recombinant plasmids are constructed by inserting a DNA fragment coding for adult T cell leukemia virus antigen peptide into a vector DNA. Microorganisms are transformed with the recombinant plasmid and thereafter cultured to express the peptide. The adult T cell leukemia virus antigen peptide is useful for the detection and diagnosis of adult T cell leukemia.
