    Fc Receptor Blocking Solution FACS

    Flow cytometric analysis was performed on THP-1 cells that were either treated with Human Fc Receptor Blocking Solution Protein, Tag Free (Cat. No. FCN-H5213) using a 1:20 dilution (5 μL of antibody stock per 1e6 cells in a final volume of 100 µL) or left untreated. All cells were stained with an irrelevant PE-conjugated mouse IgG2a antibody. PE signal was used to evaluate the blocking effect (QC tested).

バックグランド

Fc receptors expressed on the surface of immune cells such as monocytes, macrophages, dendritic cells, and certain lymphocyte subsets can bind to the Fc region of antibodies in a non‑antigen‑specific manner. This Fc–Fc receptor interaction often leads to high background signals in flow cytometry, immunofluorescence, and other immunoassays, complicating the interpretation of true antigen‑specific binding. To address this, Fc receptor blocking reagents are used prior to antibody staining to occupy Fc receptors, thereby preventing non‑specific binding and improving assay specificity and signal‑to‑noise ratio. The blocking efficiency may vary depending on the antibody isotype, Fc receptor subtype, and cell type tested.
