Monoclonal antibody to human and bovine (CD14) - biG 14



Protein G purified, lyophilized


For reconstitution add 100 µl distilled water.




Monocytes of different species and immunoaffinity purified soluble human CD14

Special note

biG 14 represents an excellent marker for CD14. The CD14 glycoprotein, gp 55, is present on most monocytic and macrophages like cell types: monocytes, macrophages, Kupffer cells, pleural phagocytic cells and dendritic reticular cells. CD14 is also observed on granulocytes and activated or transformed B-cells. Furthermore CD14 is present in a soluble form in human serum, urine and other body fluids. The CD14 molecule has been reported to be a receptor for Endotoxin.
