Product Specific Information

Reconstitution: We recommend that the vial be briefly centrifuged prior to opening to bring the contents to the bottom. Lyophilized hG-CSF should be reconstituted in sterile deionized water to 0.1-1.0 mg/mL to regain full activity. These stock solutions should be apportioned into working aliquots and stored at ≤-20°C. Further dilutions should be made in low endotoxin medium or buffered solution with FBS or tissue culture grade BSA. Storage: Lyophilized Hg-CSF should be stored at 2°C to 8°C, preferably desiccated. Store reconstituted hG-CSF at ≤-20°C (not in a frost-free freezer). Keep freeze-thaw cycles to a minimum.
Target Information
G-CSF (Granulocyte colony stimulating factor) is a naturally occurring cytokine that stimulates the production and antibacterial function of neutrophils and monocytes. Human G-CSF is an 18.8 kDa protein containing 175 amino acid residues, and a soluble isoform of the G-CSF receptor has been described. The pleotropic cytokine is produced by activated monocytes, macrophages, endothelial cells, fibroblasts, astrocytes, osteoblasts and bone marrow cells. G-CSF has been shown to have specific effects on the proliferation, differentiation and activation of hematopoietic cells. G-CSF is also expressed by various transformed cells such as carcinoma cells and myeloblastic leukemia cells. G-CSF is encoded by two distinct DNA sequences, resulting in a full size, high activity and a shorter, low activity isoform of G-CSF. G-CSF is highly conserved among species and has been shown to exert its biological functions through interaction with its receptor expressed on the surface of hematopoietic progenitors, neutrophilic granulocytes and certain carcinoma cell lines. Clinical use of G-CSF has been approved for several therapeutic applications, treatment of neonatal infections, therapy of acute myocardial infarction, granulocyte transfusion in patients with neutropenia, in severe infections and sepsis, therapy in chronic autoimmune neutropenia, treatment of acute myeloid leukemias, Sweet's syndrome and AIDS. Further, G-CSF has been shown to be a marker protein for different carcinomas such as bladder cancer and dysfunction of the protein has been linked to Kostmann Syndrome.
