Alternate Names for CD14 Antibody (M5E2) [FITC]

  • CD14 antigen
  • CD14 molecule
  • CD14
  • monocyte differentiation antigen CD14
  • Myeloid cell-specific leucine-rich glycoprotein


CD14 is a 53-55 kD glycosylphosphatidylinositol (GPI)-linked membrane glycoprotein also known as LPS receptor. CD14 is expressed at high levels on monocytes and macrophages, and at lower levels on granulocytes. Some dendritic cell populations such as interfollicular dendritic cells, reticular dendritic cells, and Langerhans cells have also been reported to express CD14. As a high-affinity receptor for LPS, CD14 is involved in the clearance of gram-negative pathogens and in the upregulation of adhesion molecules and cytokines expression in monocytes and neutrophils. The M5E2 antibody inhibits monocyte activation and cytokine production induced by LPS.
