摘要:
The present invention provides a hybrid cell line producing monoclonal antibody to an acidic fibroblast growth factor (aFGF) protein. The hybridoma is established by fusing spleen cells from immunized mice with myeloma cells. The hybridomas are cultured as clones, and antibodies obtained from the individual clones are tested for their specificity for aFGF protein. Antibodies can be obtained from the culture growth medium or from ascitic fluid of mice bearing the hybridoma tumor. Diagnostic and therapeutic uses of the monoclonal antibody are also disclosed.
摘要:
A mutein of basic fibroblast growth factors (bFGF) possesses fibroblast growth promoting activity, growth stimulating activity of capillary endothelial cells and angiogenic activity, has high stability and is low toxicity. And therefore, the present mutein is advantageously used as a healing accelerator for burns etc., a therapeutic drug for thrombosis etc., and a cell cultivation promoter.
摘要:
A mutein of basic fibroblast growth factor (bFGF) which lacks 7 to 46 amino acids of the constituent amino acids of bFGF from carboxyl terminal possesses excellent fibroblast growth promoting activities, vasoendothelial cell growth promoting activities and angiogenic activities. It is very stable in living cells. The mutein of the present invention therefore function well as a healing promoter for burns etc., therapeutic drug for thrombosis, arteriosclerosis etc., and cell cultivation promoter.
摘要:
A polypeptide comprising amino acid sequence of human interferon and that of human interleukine-2-may be produced by making new DNA by the ligation of DNA containing the structural gene coding for the peptide of human interferon with DNA containing the structural gene coding for human interleukine-2, transforming the host cells with the DNA, and cultivating the transformant.
摘要:
The present invention relates to a monclonal antibody capable of suppressing the motility of cancer cells, a polypeptide recognizable by said anti-cancer antibody and its fragment peptides which is capable of suppressing the motility of cancer cells. The present invention also relates to a production and a use for preventing the metastasis of cancer thereof.
摘要:
Disclosed herein are methods and means of producing novel deletion-type aFGF muteins, useful in the treatment of lesions, thrombosis and various diseases, by genetic engineering using parental aFGF genes.
摘要:
Disclosed are (1) a mutein of a fibroblast growth factor (FGF), the DNA having introduced therein at least one nucleotide sequence coding for a glycosylation site, (2) a DNA coding for the mutein of (1), (3) a vector containing the DNA of (2), (4) a transformant transformed with the vector of (3), and (5) a process for producing the mutein which comprises cultivating in a culture medium the transformant of a yeast or animal cell transformed with a vector of (3), and producing and accumulating the mutein of (1) in the culture medium, whereby the FGF mutein into which at least one glycosylation site has been introduced is improved in productivity, stability and activities, and advantageously used as medicine.
