•Purity: >95% by SDS-PAGE
•Endotoxin Concentration: <0.1 ng/µg Activity: ED50 <0.100 ng/mL
•Molecular Weight: 14 kDa
Reconstitution: Centrifuge the vial briefly, before opening to bring the contents to the bottom. Reconstitute the lyophilized protein in sterile, distilled water to 0.1-1.0 mg/mL to regain full activity. Apportion the reconstituted protein into working aliquots and store at ≤-20°C. Make any further dilutions of the reconstituted protein in medium or buffered solution containing carrier protein, such as PBS with 0.1% BSA.
Storage: Store the lyophilized protein at 2-8°C, preferably desiccated. Upon reconstitution, apportion into working aliquots and store at ≤-20°C (not in a frost-free freezer). Avoid repeated freeze-thaw cycles.
GM-CSF (Granulocyte-Macrophage colony-stimulating factor) is a 14.6kDa hematopoietic growth factor that exists in glycosylated and non-glycosylated biologically active forms, and stimulates the development of granulocytes, macrophages, early megakaryocytes and eosinophil progenitor cells. The active form of the GM-CSF protein is found extracellularly as a homodimer and the GM-CSF gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q-syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13. The ability of recombinant GM-CSF to increase hematopoietic cell recovery has become a focus area in the therapeutic treatment of patients following bone marrow transplantation. Recent studies have investigated GM-CSF in inflammatory and autoimmune diseases such as arthritis, arthritis related interstitial lung disease, nephritis, and psoriasis. In the CNS, GM-CSF depletion or neutralization has been studied in experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS).
