Anti-FCAR Antibody

Raised in rabbit against the Fc alpha receptor (also known as CD89), this polyclonal primary antibody from Antibodies.com targets a transmembrane glycoprotein that binds the Fc region of IgA and is expressed on myeloid lineage cells including neutrophils, monocytes, macrophages, and eosinophils.

Supplied unconjugated in a 100 µL volume, the reagent is validated for Western blot (WB) and immunohistochemistry (IHC) workflows and shows reactivity against both Human and Mouse samples, supporting translational studies that cross species boundaries.

Investigators apply the antibody to examine CD89 expression in mucosal tissues, explore IgA-driven neutrophil and monocyte activation, and probe the receptor's role in innate immune signaling and in IgA-associated conditions such as IgA nephropathy. The polyclonal format provides multi-epitope recognition, useful when surveying variable expression across different myeloid cell populations in tissue sections and lysates.
