Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) is a potent species specific stimulator of bone marrow cells. GM-CSF stimulates precursor cells of granulocytes, macrophages, and eosinophils. Murine GM-CSF is a 14.0kD protein containing 125 amino acid residues.

Biological Activity: Determined by the dose-dependent stimulation of the proliferation of murine FDC-P1 cells. The ED50 is 0.05ng/ml, corresponding to a specific activity of 2x10e7u/mg.

Responding Cells (partial list): Certain BM Precursor cells. For most in vitro applications, murine GM-CSF exerts its biological activity in the concentration range of 0.05-0.5ng/ml.

Amino Acid Sequence: The sequence of the first five N-terminal amino acids was found to be Met-Ala-Pro-Thr-Arg.

Storage and Stability:
Lyophilized powder may be stored at 4C for short-term only. For long term storage, store desiccated at -20C. Reconstituted product should be stored in working aliquots at -20C. Aliquots are stable for 12 months at 20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
