S100A8 (calgranulin A, MRP8), mouse anti human/bovine, clone S13.67 Biotin

Biotinylated monoclonal antibody to human macrophages. Possibly recognizing a scavenger receptor. Monoclonal antibody PM-2K, together with X-4 (product T-1049) and X-14 (product T-1050), forms a particular group of macrophage specific antibodies which were tested at the Vth Leukocyte Typing Workshop. The PM-2K antigen was initially suspected to function as a scavenger receptor. However, experiments with CHO cells expressing macrophage scavenger receptor (MSR) AI or AII showed no reactivity with this antibody.
