Human GBP4 (Guanylate Binding Protein 4) ELISA Kit (HUES02750)

The Human GBP4 Guanylate Binding Protein 4 ELISA Kit from Assay Genie is a quantitative sandwich immunoassay configured on a 96-well microplate. It enables researchers to measure IFN-gamma-induced guanylate binding protein levels in serum, plasma, cell culture supernatant, and other biological fluids. The colorimetric assay is read at 450 nm, with intra-assay and inter-assay precision typically reported below 10% CV. Kit components are shipped refrigerated and should be stored at 2-8 degrees C; reconstituted standards and detection antibody are kept at -20 degrees C to preserve activity. Limiting freeze-thaw cycles by aliquoting reagents is recommended. The kit is intended for research use only in vitro, supporting studies of interferon-stimulated gene expression, host defense against intracellular bacteria and parasites, inflammasome activation, and antiviral response pathways. The standard curve range typically spans 0.156-10 ng/mL, providing sensitivity suited to cytokine-induction and infection model work.
