Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, pH 7.4. Endotoxin Level <1 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Rhesus Macaque Granulocyte Macrophage Colony Stimulating Factor (rRhGM-CSF) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA. Storage & Stability Lyophilized recombinant Rhesus Macaque Granulocyte Macrophage Colony Stimulating Factor (rRhGM-CSF) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) is a monomeric glycoprotein that functions as a cytokine —it is a white blood cell growth factor[1]. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exit the circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells. GM-CSF also has some effects on mature cells of the immune system. These include, for example, inhibiting neutrophil migration and causing an alteration of the receptors expressed on the cells surface[2]. GM-CSF also plays a role in embryonic development by functioning as an embryokine produced by reproductive tract[3]. |
