The hematopoietic growth factor GM-CSF or granulocyte macrophage colony-stimulating factor, stimulates the development of neutrophils & macrophages, enhance proliferation and development of early erythroid megakaryocytic & eosinophilic progenitor cells. GM-CSF is secreted from the fibroblasts, monocytes, T-lymphocytes & endothelial cells. This protein blocks the migration of neutrophils & induces the biological activity of mature end-cells.
GMCSF Poricne Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 148 amino acids (18-144a.a.) and having a molecular mass of 16.6kDa.
GMCSF is fused to a 21 amino acid His tag at N-Terminus and purified by proprietary chromatographic techniques.
GMCSF protein solution (0.5mg/ml) containing Phosphate-Buffered Saline (pH7.4).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
The ED50 range is ≤ 40 ng/ml, and is measured in a cell proliferation assay using TF-1 human erythroleukemic cells.
