GM-CSF (granulocyte-macrophage colony-stimulating factor) is a haematopoietic growth factor which exists in both glycosylated and non-glycosylated biologically active forms, and stimulates the development of granulocytes, macrophages, early megakaryocytes and eosinophil progenitor cells. The ability of recombinant GM-CSF to increase haematopoietic cell recovery has become a focus area in the therapeutic treatment of patients following bone marrow transplantation.
- Target Species
- Product Form
- Purified recombinant protein - lyophilized
- Reconstitute with 0.2 ml distilled water. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. For extended storage, the addition of 0.1% bovine serum albumin (BSA) is recommended.
- Purified recombinant GM-CSF expressed in E. coli
- Preservative Stabilisers
- 10mM Sodium citrate pH3.5
- Carrier Free
- The ED50 as determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is ≤ 0.1 ng/ml, corresponding to a specific activity of ≥ 1 x 107 units/mg.
- >98% by SDS PAGE/HPLC
- Approx. Protein Concentrations
- 0.1 mg/ml after reconstitution
- Protein Molecular Weight
- 14.6 kDa (128 amino acid residues)

- Prior to reconstitution store at -20oC. Following reconstitution store at -20oC.
This product should be stored undiluted.
Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.
- Guaranteed for 3 months from the date of reconstitution or until the date of expiry, whichever comes first. Please see label for expiry date.
