The lyophilized antibody is stable for at least 1 year from date of receipt at -20 °C. Upon reconstitution, this antibody can be stored in working aliquots at - 8 °C for one month, or at -20 °C for six months without detectable loss of activity.
G-CSF is secreted by monocytes, macrophages, and neutrophils after cell activation. It is produced also by stromal cells, fibroblasts, and endothelial cells. Epithelial carcinomas, acute myeloid leukemia cells and various tumor cell lines. The synthesis of G-CSF can be induced by bacterial endotoxins, TNF, IL1 and GM-CSF. Comparison of the primary sequence of G-CSF with those of the two other colony stimulating factors, GM-CSF and M-CSF, shows that the three factors are not related to each other. Murine and human G-CSF show a sequence homology of approximately 70 % at the DNA level and of 72 % at the protein level. The G-CSF receptorCD114, is expressed on all cells of the neutrophils and granulocytes lineage. It is expressed also in placenta cells, endothelial cells and various carcinoma cell lines. Human G-CSF is active in murine cells and vice versa. G-CSF stimulates the proliferation and differentiation of hematopoietic progenitor cells committed to the neutrophils and granulocytes lineage in a dose-dependent manner.G-CSF synergises with some other cytokines, including GM-CSF and IL4. GM-CSF and G-CSF are required, for example, to develop neutrophilic colonies in vitro. The concerted action of G-CSF and Epo is required to support the growth of mixed colonies of the early erythroid progenitors. A combination of IL4 with G-CSF has been shown to lead to synergistic suppression of the growth of some human leukemic cell lines.
