This receptor is present on the surface of myeloid lineage cells such as neutrophils, monocytes, macrophages, and eosinophils, especially phagocytes located in mucosal areas.

By ELISA this antibody reacts specifically with Human IgG. Has cross-reactivity in ELISA with Human IgG1, Human IgG2, Human IgG3, Human IgG4. May has cross-reactivity with the immunoglobulins of other species.  Has cross-reactivity with rabbit IgG, rat IgG (>10%), horse IgG (3.5%), guinea pig IgG (3.6%), human IgM (2.2%).  Minimal cross-reactivity with mouse IgG, bovine IgG.
