摘要:
A recombinant non-glycosylated mammalian growth factor (BTC-GF) stimulates proliferation of human smooth muscle cells. Especially, the amino acid sequence of the protein deduced from the nucleotide sequence coding for human BTC-GF is as that comprising the amino acids No. 1 to No. 147 of Figure 10 or the amino acids No. 1 to 80 of Figure 10, and the amino acid sequence of the protein deduced from the nucleotide sequence coding for mouse BTC-GF is as that comprising the amino acids No. 1 to No. 146 of Figure 9.
摘要:
The present invention provides a polypeptide represented by the following amino acid sequence: wherein n is 0 or 1 and X represents or a fragment thereof (n = 0: SEQ ID NO:1, n = 1: SEQ ID NO:2), a recombinant DNA coding for the polypeptide, a vector containing the recombinant DNA, the preparation of a transformant carrying the vector, and the production of the polypeptide with the transformant. The invention also provides a method for promoting an increase in the number of platelets in a mammal using a polypeptide having a heparin binding secretory transforming factor 2 (hst-2) activity. The polypeptide can be produced in large amounts, and has hst-2 activity, so that it can be advantageously used as drugs for promoting treatment of burns, wounds, etc., and therapeutic agents for gastrointestinal ulcers. Further, it can be utilized as platelet-increasing agents.

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 human basic fibroblast growth factor (hbFGF), which is usable for a cure promoter for burns etc., therapeutic agent for thrombosis etc. or a reagent for promoting cell cultivation, can be produced in a large quantity by cultivating a transformant as transformed with a vector including a DNA coding the hbFGF.
摘要:
The present invention presents a DNA containing a synthetic gene for expression of human epidermal cell growth factor of the DNA sequence: The adoption of the DNA of the present invention improves the stability of mRNA, the translation efficiency and the influence of the high-dimensional structure which is determined by the mRNA sequence, and made it possible to produce hEGF efficiently.
摘要:
This invention relates to animal cells transformed with a DNA having a region coding for a human IL-2 protein and, upstream therefrom, at least one promoter and to a method of producing such human IL-2 protein which comprises cultivating said transformants to thereby cause production and accumulation of said protein in the culture and recovering the same.
摘要:
Rat protein kinase C, recombinant DNA containing DNA sequence coding for rat kinase C, a transformant transformed with a vector containing the above recombinant DNA, and the production method of rat kinase C cultivating the transformant are disclosed. Rat kinase C is useful as reagent for studying cellular signal transduction mechanism, as diagnostic and inspection agent for disease, for example tumor, resulting from the trouble of cellular signal transduction mechanism, and as screening agent for a preventive agent or medicine to the disease.
摘要:
A deletion type mutein of heparin-binding secretory transforming factor (hst-1) possesses excellent cell growth promoting activity and is stable. The present mutein can therefore be used as a therapeutic medicine such as a healing promoter for burns, wounds, surgical injuries etc.
