Anti-Human G-CSF (Clone 3316)

Purified Recombinant Human G-CSF (Accession # NP_757373)

This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.4 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.

The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months.

Neutralization: This antibody is useful for neutralization of Human G-CSF bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Human G-CSF (at 0.125 ng/ml) is 0.01 - 0.03 µg/ml.

Mouse Anti-Human G-CSF (Granulocyte Colony Stimulating Factor) (Clone 3316) recognizes an epitope on Human G-CSF. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Granulocyte colony-stimulating factor (G-CSF or GCSF) is a colony-stimulating factor hormone. It is a glycoprotein, growth factor or cytokine produced by a number of different tissues to stimulate the bone marrow to produce granulocytes and stem cells. G-CSF then stimulates the bone marrow to release them into the blood. It also stimulates the survival, proliferation, differentiation, and function of neutrophil precursors and mature neutrophils. G-CSF is produced by endothelium, macrophages, and a number of other immune cells. It stimulates the production of white blood cells. G-CSF is also used to increase the number of hematopoietic stem cells in the blood of the donor before collection by leukapheresis for use in hematopoietic stem cell transplantation.
