Hu Recom G-CSF, 1000 µg

STEMCELL Technologies supplies a Human Recombinant G-CSF produced through E. coli expression. The cytokine stimulates the initial proliferation of granulocyte-macrophage progenitors and supports the survival of erythroid and eosinophil progenitors. Biological activity is assessed by the protein's ability to promote proliferation of mouse NFS-60 cells, with cell proliferation measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum, and is 0.053 ng/mL in the cited example. The protein has a predicted molecular mass of 18.8 kDa. The product is referenced for research workflows including immunomagnetic positive selection of human CD14+ cells, immunomagnetic negative selection of human myeloid dendritic cells, and immunomagnetic negative isolation of untouched human monocytes directly from whole blood.
