ICAM-1 ELISA Kit (Intercellular Adhesion Molecule-1)


Human ICAM-1 ELISA kit can be used for measuring in vitro quantitative amounts of intercellular adhesion molecule-1 (CD54, ICAM-1) in human plasma, cell culture supernatant, cell lysates, serum and many other biological fluids. This assay has a minimum sensitivity limit of 10.0 pg/ml.


Intercellular adhesion molecule-1 (ICAM-1, ICAM1 or CD54) contains 3 domains; a single transmembrane domain, cytoplasmic domain and an extracellular domain. The extracellular domain possesses many loops which are due to disulphide bridges present. It is important in facilitating leukocyte endothelial transmigration and in stabilising cell-cell interactions. It is a ligand for LFA-1 (integrin), a vital receptor present on leukocytes and it can also interact with CD18, CD11a and EZR.

ICAM-1 possesses a tissue distribution which is very similar to that of many other major histocompatibility complex class II antigens, this is likely to be crucial in a number of inflammatory responses. The dominant secondary structure for this protein is of a beta sheet with the possibility of dimerization domains.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
