Assay Principle
This sandwich ELISA quantifies mouse granulocyte-macrophage colony-stimulating factor (gene Csf2) in cell culture supernatants, cell lysates, serum and plasma (heparin, EDTA). Strips are pre-coated with a capture antibody. After the sample is added, a biotinylated detection antibody binds the captured protein, and an avidin–biotin–peroxidase complex supplies the enzyme. TMB develops color in proportion to the bound target; the reaction is stopped and read at 450 nm, and concentrations are read from the standard curve.
GM-CSF (CSF2) is a cytokine that drives the growth and differentiation of hematopoietic progenitors into granulocytes, macrophages and other myeloid cells. Produced by T cells, macrophages, endothelial cells and fibroblasts, it also activates mature myeloid cells, so it is a frequent target in studies of inflammation, autoimmunity and dendritic cell culture.
