Monoclonal antibody to human and bovine monocytes (CD14)
- biG 13



Protein G purified, lyophilized


For reconstitution add 100 µl water to get concentration of 1 mg/ml in PBS




Monocytes of different species and immunoaffinity purified soluble human CD14

Special note

biG 13 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. Repeated freezing and thawing should be avoided.


20 µg/ml inhibits binding of 0.5 µg/ml LPS to CD14, binding epitope amino acid 9-13, 39-44, cross reacting with CD14 of cattle++, swine ++, dog+ horse+
Binding titre at human CD14 transfected CHO-cells: more than 10.000


Suitable for immunostaining of CD14 positive cells (flow cytometry) ELISA, CD14 inhibition studies, Western Blot


Long time storage at -20°C or -80°C


100 µg in PBS without NaN3 or other stabilisation before lyophilisation

IgG-content 1 mg/ml PBS
