Granulocyte Colony Stimulating Factor Recombinant Protein

GCSF or CSF3, is a glycoprotein that is produced and secreted by macrophages stimulated with endotoxin. It is also 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 pulse them out of the marrow into the blood. It also stimulates the survival, proliferation, differentiation, and function of neutrophil precursors and mature neutrophils. The natural human GCSF exists in two forms, a 174- and 180aa-long protein (precursor 204aa, mature peptide 175aa; chromosome 17q11.2-q12, ~19.6kD). The more-abundant and more-active 174aa form has been used in the development of pharmaceutical products (Available under the names Neupogen or Granulokine (Amgen/Roche) and Granocyte (Rhone-Poulenc). GCSF is used to treat neutropenia (a disorder characterized by an extremely low number of neutrophils in blood). The PEG (polyethylene glycol) form has a much longer half-life, reducing the necessity of daily injections. G-CSF stimulates the production of white blood cells. Recombinant G-CSF is used in certain cancer patients to accelerate recovery from neutropenia after chemotherapy, allowing higher-intensity treatment regimens. G-CSF is also used to increase the number of hematopoietic stem cells in the blood before collection by leukapheresis for use in hematopoietic stem cell transplantation.

GCSF mRNA is alternatively spliced to produce 2 isoforms. Isoform 1 (mature peptide 175aa or long form) and isoform 2 (short form, missing 66-68aa). Both forms have authentic GCSF activity.

Small volumes of Granulocyte Colony Stimulating Factor, Recombinant, Mouse, Western Blot Positive Control recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
