Calprotectin ELISA kits are assays designed to detect the calprotectin protein complex, which is made up of S100 calcium-binding proteins A8 and A9. This 24-kDa dimer is involved in metal sequestration, particularly for iron, zinc and manganese, allowing for antimicrobial action. It is used as a biomarker for conditions such as inflammatory bowel syndrome (IBS), colorectal cancer and colitis. Calprotectin ELISA kits can be used for faecal calprotectin detection.
