Description: This SAFE™ (Serum and Animal Free, low Endotoxin) protein has been made in plants with no exposure to animal protein during expression or purification. This animal free product has very low levels of endotoxin.
Human GM-CSF (Granulocyte/Monocyte-Colony Stimulating Factor) is a differentially glycosylated factor produced mainly by activated T cells and macrophages. Endothelial cells and fibroblasts can also produce GM-CSF after exposure to TNF alpha, IL-1, IL-2 and IFN gamma. GM-CSF is found associated with extracellular matrix and in membrane-bound formats too. GM-CSF stimulates proliferation, activation and differentiation of macrophages and granulocytes and their progenitors.
Applications Reported: SAFE™ Human GM-CSF Recombinant Animal Free Protein is biologically active.
Applications Tested: The ED50 of this protein, as measured by TF-1 cell proliferation assay, is less than 0.2 ng/mL. This corresponds to a specific activity of greater than or equal to 5 x 10e6 Units/mg.
Source: Plant expressed 127 amino acids (Ala18-Glu144). accession NP_000749.2.
Bioactivity: The ED50 of this protein, as measured by TF-1 cell proliferation assay, is less than 0.2 ng/mL. This corresponds to a specific activity of greater than or equal to 5 x 10e6 Units/mg.
Endotoxin: Less than 0.005 ng/ug (0.05 EU/ug) as measured by turbidity assay. Purity: Greater than or equal to 95% as determined by SDS-PAGE.
Molecular Weight: 26 kDa with glycosylation.
Storage: The lyophilized powder can be stored at less than or equal to -20°C. (Short term storage at 2-8°C). Reconstitute in sterile reagent grade deionized water to a concentration no less than 100 µg/mL. Once reconstituted, protein should be aliquoted and stored at -20°C or lower. For best stability add 0.1% BSA before freezing aliquots.
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).
