Recombinant Mouse ICAM-1/CD54 Fc Chimera Protein, CF Summary
| Details of Functionality |
Measured by the ability of the immobilized protein to support the adhesion of PMA-stimulated HSB2 human peripheral blood acute lymphoblastic leukemia cells. When 5 x 10 4 cells/well are added to rmICAM/Fc Chimera coated plates (12.5 µg/mL with 100 µL/well), approximately 65-95% will adhere after 1 hour incubation at 37 degreesC. Optimal dilutions should be determined by each laboratory for each application. |

Background
Intercellular Adhesion Molecule-1 (ICAM-1, CD54) binds the leukocyte integrins LFA-1 and Mac-1. ICAM-1 expression is weak on leukocytes, epithelial and resting endothelial cells, as well as some other cell types, but expression can be stimulated by IFN-gamma , TNF-alpha , IL-1 beta and LPS. Mouse and human ICAM-1 share approximately 54% amino acid identity. Soluble ICAM-1 is found in a biologically active form in serum, probably as a result of proteolytic cleavage from the cell surface, and is elevated in patients with various inflammatory syndromes such as septic shock, leukocyte adhesion deficiency syndrome (LAD), cancer and transplantation.
