Introduction |
GMCSF is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This 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.
GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes. |
|
Description |
Granulocyte Macrophage Colony Stimulating Factor Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 125 amino acids and having a molecular mass of 14285.35 Dalton.
GM-CSF Mouse is purified by proprietary chromatographic techniques. |
|
Source |
Escherichia Coli. |
|
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
|
Formulation |
GM-CSF Mouse was lyophilized with no additives. |
|
Solubility |
It is recommended to reconstitute the lyophilized Granulocyte Macrophage Colony Stimulating Factor in sterile 20mM AcOH (acetic Acid) not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
|
Stability |
Lyophilized Granulocyte Macrophage Colony Stimulating Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GM-CSF should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles. |
|
Purity |
Greater than 98.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE. |
|
Amino acid sequence |
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Ala-Pro-Thr-Arg. |
|
Biological Activity |
The ED50 as determined by the dose-dependant stimulation of the proliferation of murine FDC-P1 cell line is < 0.2 ng/ml, corresponding to a Specific Activity of 5,000,000 IU/mg. |
|
Protein content |
GM-CSF quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm using the absorbency value of 0.765 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of GM-CSF as a Reference Standard. |

Applications: GM-CSF as tested a therapeutic potential in a murine model of pulmonary aspergillosis. In summary, this pilot study indicates that GM-CSF administered intranasally may be a novel therapeutic approach for the prevention or treatment of pulmonary fungal infections and may augment the efficacies of antifungal agents.
GM-CSF was given intranasal.
