Anti-GM-CSF Antibody [429]

This biotinylated mouse monoclonal reagent from Antibodies.com targets human Granulocyte Macrophage Colony Stimulating Factor (GM-CSF), a 23 kDa cytokine that drives the proliferation and differentiation of myeloid progenitor cells into granulocytes and macrophages. Clone 429 is supplied as a 100 µL liquid preparation with an IgG1 isotype, conjugated to biotin for use as a detection antibody in ELISA workflows. The reagent recognizes the human GM-CSF protein and is used in cytokine quantification studies across immunology and inflammation research, where GM-CSF levels serve as a biomarker for immune activation. Investigators in asthma, autoimmune disease, and tumor microenvironment studies have applied clone 429–based detection to characterize cytokine release in cellular and clinical samples. The biotin conjugate format pairs with standard streptavidin-HRP chemistry. Refrigerated storage preserves biotin activity across repeated use.
