Development and characterization of antiserum to murine granulocyte-macrophage colony-stimulating factor

; ; ; ;
The expression in yeast of a cDNA clone encoding murine granulocyte-macrophage colony-stimulating factor (GM-CSF) has made possible the purification of large quantities of this recombinant protein. Rabbits immunized with pure recombinant GM-CSF generated antibodies that were shown to be specific for both recombinant GM-CSF and GM-CSF isolated from natural sources. Other lymphokines, including IL 1..beta.., IL 2, IL 3, and recombinant human GM-CSF did not react with the antiserum. The antiserum together with recombinant GM-CSF that had been radiolabeled with /sup 125/I to high specific activity, formed the foundation for a rapid, sensitive, and quantitative radioimmunoassay specific for murine GM-CSF. Furthermore, the antiserum was found to inhibit the biologic activities of GM-CSF as measured in both a bone marrow proliferation assay and a colony assay, and thus should prove to be a useful reagent for dissecting the complex growth factor activities involved in murine hematopoiesis.
