Cayman’s Annexin A1 (human) ELISA Kit is a sandwich assay which can be used to measure human annexin A1 in tissue culture media, serum and plasma. The standard curve spans the range of 0.20 - 20 ng/ml. Annexin A1 is a natural anti-inflammatory protein produced by neutrophils and monocytes. The glucocorticoid-induced production and release of annexin A1 is the primary means by which glucocorticoids function as anti-inflammatory agents. Annexin A1 inhibits the synthesis of pro-inflammatory eicosanoids by suppressing the function of secretory phospholipase A2 (sPLA2). This, in turn, limits the recruitment of neutrophils into inflammatory sites and down-regulates the production of pro-inflammatory mediators by those neutrophils that enter inflammatory sites. Annexin A1 also functions in the resolution of inflammation by inducing neutrophil apoptosis, and promoting neutrophil clearance (efferocytosis) by macrophages. The pro-resolving functions of annexin A1 are mediated via binding to FPR2/ALX, a receptor it shares with the specific pro-resolving mediators lipoxin A4 (LXA4) and resolvin D1 (RvD1).
