Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of a mammalian (e.g., human) pluripotent granulocyte colony-stimulating factor ("hpG-CSF") which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Sequences coding for part or all of the sequence of amino acid residues of hpG-CSF or for analogs thereof may be incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Products of expression of the DNA sequences display, i.e., the physical and immunological properties and in vitro biological activities of isolates of hpG-CSF derived from natural sources. Disclosed also are chemically synthesized polypeptides sharing the biochemical and immunological properties of hpG-CSF.
A purified and isolated DNA molecule for use in securing expression in a procaryotic or eucaryotic host cell of a polypeptide product having at least a part of the primary structural conformation and the hematopoietic biological activity of naturally-occurring pluripotent granulocyte colony-stimulting factor, said DNA selected from among:
A purified and isolated DNA molecule coding for procaryotic or eucaryotic host expression of a polypeptide product having part or all of the primary structural conformation and the hematopoietic biological activity of human pluripotent granulocyte colony-stimulating factor.
A purified and isolated DNA molecule coding for a polypeptide fragment or polypeptide analog of naturally-occurring pluripotent granulocyte colony-stimulating factor and possessing the hematopoietic biological activity thereof.
