Application Notes
The antibody B-A8 has been tested as the capture antibody in a sandwich ELISA for analysis of human CD14 in combination with antibody MEM-18, NB500-374. Immunohistochemistry (paraffin sections) - Positive staining on human PML brain sections was mainly observed on monocytes in the lumenal side of brain blood vessels, and on some perivascular cells adjacent to medium-sized vessels. Heat retrieval of antigen is recommeded.

Alternate Names for CD14 Antibody (B-A8)

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


CD14 is a single copy gene encoding 2 protein forms: a 50 to 55 kDa glycosylphosphatidylinositol anchored membrane protein (mCD14) and a monocyte or liver derived soluble serum protein (sCD14) that lacks the anchor. Both molecules are critical for lipopolysaccharide (LPS) dependent signal transduction, and sCD14 confers LPS sensitivity to cells lacking mCD14. Increased sCD14 levels are associated with inflammatory infectious diseases and high mortality in gram negative shock. CD14 also appears to be involved in clearance of gram-negative bacteria via its high affinity binding to LPS-LPB complexes.
