Recombinant Rat ICAM-1/CD54 Fc Chimera Protein, CF
Recombinant Rat ICAM-1/CD54 Fc Chimera Protein, CF Summary
When 5 x 104 cells/well are added to rrICAM/Fc Chimera coated plates (12.5 µg/mL with 100 µL/well), >20% will adhere after 1 hour incubation at 37 °C.
Also supports adhesion (40-70%) of PMA treated rat Nb-211 cells when coated at 12.5 µg/mL.
Optimal dilutions should be determined by each laboratory for each application.
(Gln28 - Thr493)
Accession # Q00238
|DIEGRMD||Human IgG1 |
(Pro100 - Lys330)
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

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. Rat and human ICAM-1 share approximately 52% amino acid identity. Rat and mouse ICAM-1 share approximately 52% 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.
