Descripción

Descripción general

ICAM1 (intercellular adhesion molecule 1) was initially identified as a ligand for the β2 integrin lymphocyte function-associated antigen (LFA)-1. It is a glycoprotein with a 90,000-110,000Mr molecular weight, and shows wide range of tissue expression, including tissue macrophages and dendritic cells. It also shows expression on non-hematopoietic cells such as vascular endothelial cells, epithelial cells of thymus and mucosa, and dermal fibroblasts. It is a member of the ICAM family, which also include ICAM-2, -3, -4 and -5.[1][2]
Recombinant human ICAM-1 is a 49.5 kDa glycoprotein comprising the extracellular domain (453 amino acid residues) of ICAM-1. Monomeric glycosylated ICAM-1 migrates at an apparent molecular weight of approximately 72.0-80.0 kDa by SDS-PAGE analysis under reducing conditions.

Acciones bioquímicas o fisiológicas

The expression of ICAM1 (intercellular adhesion molecule 1) is strongly increased by IL-1 (interleukin) and interferon (IFN)-γ. It is expressed on lymphoid cells where it is required for phorbol ester-induced aggregation. It participates in LFA-1 (lymphocyte function-associated antigen)-dependent NK (natural killer) cell stimulation through its attachment to actin cytoskeleton through α-actinin or ezrin. It also acts as the receptor for rhinovirus, a common cold virus and Plasmodium falciparum.[2] Soluble ICAM-1 levels are elevated in pregnant women with gestational diabetes mellitus (GDM), which is an outcome of endothelial cell activation and dysfunction.[3] Meta-analysis of case-control studies show that rs1799969 polymorphism in ICAM-1 gene is linked with increased susceptibility to cancer.[4]

Lyophilized from 10 mM Sodium Phosphate, pH 7.5.

Reconstitución

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
