ProSpec-GMCSF Porcine

CSF-2, MGI-1GM, GM-CSF, Pluripoietin-alpha, Molgramostin, Sargramostim.

GMCSF is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of GMCSF is found extracellularly as a homodimer. GMCSF 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.

Granulocyte Macrophage-Colony Stimulating Factor Porcine Recombinant produced in E. coli is a non-glycosylated monomer chain containing 128 amino acids and having a  molecular mass of 14.5kDa.

GMCSF is purified by proprietary chromatographic techniques.

Escherichia Coli.

Sterile Filtered White lyophilized powder.

The protein was lyophilized from a sterile filtered solution containing 10mM sodium phosphate, pH 7.5.

It is recommended to reconstitute the lyophilized GMCSF in sterile 18MΩ-cm H₂O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized GMCSF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GMCSF should be stored at 4°C between 2-7 days and for future use below -18°C.

Please prevent freeze-thaw cycles.
