G-CSF Protein, Mouse (CHO)

G-CSF Protein, Mouse (CHO) is a polypeptide growth factor that regulates the production of neutrophilic granulocytes.

Granulocyte Colony Stimulating Factor (G-CSF) is a cytokine that normally acts in the bone marrow microenvironment to stimulate blood cell formation. It selectively promotes growth and maturation of neutrophil progenitor cells. Granulocyte Colony Stimulating Factor receptors are present on precursor cells in the bone marrow. By binding to these receptors, Granulocyte Colony Stimulating Factor initiates proliferation and differentiation into mature granulocytes, and also stimulates bone marrow cell release into the circulation. In addition to growth promotion, Granulocyte Colony Stimulating Factor also effects phagocytosis, motility, bactericidal activity and surface molecule expression of neutrophils and monocytes^[1][2]. G-CSF production is induced by several inflammatory stimuli that become rapidly elevated during infection such as interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNFα) and lipopolysaccaride (LPS). Therefore, pathogen-mediated activation of host pattern recognition receptors via LPS, and the host cytokine response to infection, serve to induce circulating levels of G-CSF^[3].

The ED₅₀ is 10-60 pg/mL as measured in a cell proliferation assay using M-NFS-60 mouse myelogenous leukemia lymphoblast cells.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
