title: Molecular cloning, expression in Escherichia coli and production of bioactive homogeneous recombinant human granulocyte and macrophage colony stimulating factor.
abstract: Human granulocyte and macrophage colony stimulating factor (hGM-CSF) is a glycoprotein that activates and enhances the differentiation and survival of neutrophils, eosinophils and macrophages, which play a key role in the innate immune response. Here we describe the construction of the hGM-CSF encoding gene, cloning, expression in Escherichia coli, purification of recombinant hGM-CSF, N-terminal amino acid sequencing, and biological activity assay using TF-1 cells. The results presented show that the combination of experimental strategies employed to obtain recombinant hGM-CSF can yield biologically active protein, and may be useful to scaling-up production of biosimilar protein.
