The antibody was purified by affinity chromatography and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
MRP-14, also known as S100A9, belongs to the S100 family of proteins containing 2-EF-hand calcium-binding motifs. It forms non-covalently associated complexes with another S100 family member, MRP-8. MRP14 is expressed in neutrophils and monocytes, it also has been found in ileal tissue eosinophils. The S100A8/A9 complex has been shown to play a role during calcium-dependent activation as well as have antibacterial, antifungal, immunomodulating, and anti-proliferative effects. It also functions as a chemoattractant factor for neutrophils and has been considered an endogenous activator of Toll-like receptor 4. S100A9 has been identified as a marker for CD14(+) HLA-DR(-/low) MDSCs.
