Extended validation for S100A8 Antibody, anti-human, REAfinity™


Other clonesOverlap in epitope recognition with REA917
Cells were incubated with an excess of purified unconjugated S100A8 (REA917) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Specifications for S100A8 Antibody, anti-human, REAfinity™


Clone REA917 recognizes the calcium- and zinc-binding protein S100A8, also known as migration inhibitory factor-related protein 8 (MRP-8), calprotectin, or calgranulin-A. S100A8 is mainly expressed in myeloid cells, e.g., monocytes, macrophages, and granulocytes and upregulated in different tumors, e.g., in skin, breast, colon, pancreatic, bladder, and ovarian malignancies. S100A8 is involved in the regulation of inflammatory processes and immune response and plays a role in antimicrobial, cytostatic, and chemotactic activities.
Additional information: Clone REA917 displays negligible binding to Fc receptors.
