TRACP/PAP/ACP5 Luminex Assays

TRACP is an iron-containing, 35 kDa glycoprotein that hydrolyses phosphomonoesters. It is produced as a monomer by osteoclasts and is cleaved by cathepsins to create a disulfide-linked dimer that acts on bone matrix phosphoserine-containing proteins in lysosomal vesicles. Following phosphate cleavage, TRACP is released from the cell where it serves as a marker of bone resorption.
