| Scientific Background: | The myeloid differentiation antigen CD14 acts as the major receptor for bacterial LPS. The dominant form of the recombinant wildtype CD14 ist the 50kDa protein.
The CD14 glycoprotein, gp 55, is present on most monocytic and macrophage 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 it is present in a soluble form in mouse serum, urine and other body fluids. |

| Regulatory Status: | RUO - Research Use Only |
