A cloned single-strand DNA encoding amino acid sequence for a eukaryotic transcription factor S-II is disclosed together with, a cloned double-strand DNA consisting of the single-strand DNA and its complementary single-strand DNA, a DNA fragment of the single- or double-strand DNA, a process for the preparation thereof, a plasmid, in which the double-strand DNA or its fragment is inserted, and a diagnosis of viral diseases and cancers.

Cloning of DNA encoding transcription factor S-II and utilization of the

An antibacterial polypeptide is disclosed, which is immunologically produced by Sarcophaga peregrina, when the insect is injured in its body wall. The polypeptide has a molecular weight of about 7000.

Antibacterial polypeptides from Sarcophaga peregrina

A cloned single-strand DNA comprising nucleotide sequence which encodes an antibacterial polypeptide precursor, a cloned double-strand DNA consisting of the single-strand DNA and its complementary single-strand DNA, a DNA fragment of the single- or double-strand DNA, a process for the preparation thereof, and a plasmid, in which the double-strand DNA or its fragment is inserted.

Cloning of a DNA sequence encoding a Sarcophaga peregrina antibacterial

A cloned single-strand DNA encoding amino acid sequence for a eukaryotic transcription factor S-11 is disclosed together with, a cloned double-strand DNA consisting of the single-strand DNA and its complementary single-strand DNA, a DNA fragment of the single- or double-strand DNA, a process for the preparation thereof, a plasmid, in which the double-strand DNA or its fragment is inserted, and a diagnosis of viral diseases and cancers.

Cloning of DNA encoding transcription factor S-11

A cloned single-strand DNA comprising nucleotide sequence which encodes an antibacterial polypeptide precursor, a cloned double-strand DNA consisting of the single-strand DNA and its complementary single-strand DNA, a DNA fragment of the single- or double-strand DNA, a process for the preparation thereof, and a plasmid, in which the double-strand DNA or its fragment is inserted are disclosed.

Cloning of DNA encoding antibacterial polypeptide precursor

A biologically active polypeptide, method of obtaining same and use thereof are disclosed. The polypeptide is obtained through steps of cultivating a cell line established from Sarcophaga peregrina embryo to produce the same in a culture medium, as product of the cell line, isolating and purifying the same. The polypeptide shows an anti-virus activity.

Biologically active polypeptide and use thereof

A lectin like protein substance, method of obtaining same and a pharmaceutical agent containing the substance, as an effective ingredient. The substance is obtained through steps of cultivating a cell line stablished from Sarcophaga peregrina embryo to produce the substance in a culture medium, as product of the cell line, separating the refining the same. The substance shows an anti-tumor activity and thus is useful as an effective ingredient for medicines to cure cancers.
