Novus' biologically active proteins are stringently purified to provide only the safest and most highly effective proteins available. This protein was expressed in E. coli, purified by HPLC, QC tested by SDS-PAGE and Western Blot and validated on appropriate cell lines for bioactivity. All HPLC and bioactivity data is provided for your assurance.
|Details of Functionality
G-CSF Protein is fully biologically active when compared to standard. The ED50 determined by a cell proliferation assay using murine NFS-60 cells is less than 0.05 ng/ml, corresponding to a specific activity of > 2.0 x 10^7 IU/mg
| Protein/Peptide Type
Biologically Active Protein
> 97 % pure by SDS-PAGE and HPLC
Less than 0.1 EU/ug of endotoxin as determined by LAL method.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Packaging, Storage & Formulations
Store at 4C after rehydration. For extended storage after rehydration, add an equal volume of glycerol and store at -20C. Avoid repeated freeze-thaw cycles.
Lyophilized from a 0.2 um filtered concentrated solution in 5 mM Sodium Citrate, pH 4.0.
> 97 % pure by SDS-PAGE and HPLC
Briefly centrifuge vial prior to opening. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < or = -20 C.
This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.
Alternate Names for Recombinant Rat G-CSF Protein
- chromosome 17 open reading frame 33
- colony stimulating factor 3 (granulocyte)
- granulocyte colony-stimulating factor
Granulocyte colony stimulating factor (G-CSF) is a pleiotropic cytokine. It is mainly produced by monocytes and macrophages upon activation by endotoxin, TNF-alpha and IFN-gamma. Besides, many other cell types can secreted this protein after LPS, IL-1 or TNF- alpha activation, which are fibroblasts, endothelial cells, astrocytes and bone marrow stromal cells. Various carcinoma cell lines and myeloblastic leukemia cells can express G-CSF constitutively. G-CSF is cytokine that acts in hematopoiesis by controlling the production, differentiation and function of 2 related white cell populations of the blood, the granulocytes and the monocytesmacrophages. In addition, it may function in some adhesion or recognition events at the cell surface.
