Sargramostim, rGM-CSF (Leukine), isa glycoprotein commercially produced in genetically engineeredyeast cells. Its polypeptide chain contains 127 aminoacids. It differs from the natural hormone by substitution ofleucine at position 23 and variations in the glycosylation.94Sargramostim is a lineage-nonspecific hematopoietic factor,because it promotes the proliferation and maturation ofgranulocytes (neutrophils and eosinophils) and monocytes(macrophages and megakaryocytes).The primary indication for sargramostim is in myeloidengraftment following autologous bone marrow transplantationand hematopoietic stem cell transplantation. Handling,storage precautions, and adverse effects are similar to thosefor filgrastim.
