Anti-FCGR1A Antibody

Targeting the high-affinity IgG receptor FCGR1A (also known as CD64), this unconjugated rabbit polyclonal reagent from Antibodies.com is supplied as 100 µl at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol. Validated for Western blot, immunohistochemistry, and immunofluorescence workflows on human samples, the antibody is intended for research use only and supports detection of CD64-expressing myeloid populations, including monocytes, macrophages, and interferon-gamma-activated neutrophils commonly investigated in autoimmune and inflammatory disease studies.

The polyclonal format provides recognition of multiple epitopes across the FCGR1A extracellular domain, supporting reproducible staining across tissue sections and cell preparations. The glycerol-supplemented formulation remains liquid at storage temperatures of -20 °C and resists freeze-thaw damage during repeated experimental cycles. Without a fluorophore or enzyme label, the antibody integrates cleanly into custom labeling protocols, biotinylation procedures, and signal amplification strategies such as tyramide-based detection.
