摘要:
A T cell-derived colony stimulating factor (TC-CSF) may be isolated from media conditioned with T lymphocyte cells. TC-CSF stimulates formation of colonies composed of granulocytes, macrophages, megakaryocytes, fibrocytic stromal cells, lymphocytes, and mixed colonies of granulocytes and macrophages. Anion exchange chromatography may be employed in conjunction with gel filtration and rpHPLC to isolate TC-CSF. Human TC-CSF and murine TC-CSF cDNA, mRNA, genomic DNA nucleotide and amino acid sequences, expression products, pharmaceutical formulations and antibody materials are specifically provided.

摘要:
Cysteine added variants ("CAVs") of EPO are provided having one or more cysteine residues substituted for selected naturally occurring amino acid residues, or inserted into the polypeptide sequence, and preferably being further modified by deletion of certain N-terminal amino acids. Such CAVs may be additionally modified by the coupling of sulfhydryl reactive compounds to the introduced cysteine residue(s) without loss of bioactivity to produce selected homogeneously modified EPO and improved pharmaceutical compositions containing the same.
摘要:
A method of preparing a crystalline form of recombinant human granulocyte-macrophage colony-stimulating factor (r-h-GM-CSF) using polyethylene glycol with molecular weight of about 8000.
摘要:
Plasmid vectors that carry complementary DNA (cDNA) clones coding for polypeptides exhibiting human granulocyte/macrophage colony stimulating factor activity, including eosinophil growth factor activity. One of these polypeptides is about 144 amino acids in length, including a potential leader sequence. The cDNA is derived from messenger RNA isolated from a human cell source after activation with concanavalin A. The cDNA was cloned by incorporation into a plasmid vector, which was then transformed into E. coli. The plasmid vector also contained DNA segments from the SV40 virus, permitting expression of the cDNA after transfection into a mammalian host cell, such as monkey COS-7 cells.
