This is a research-grade, unconjugated non-therapeutic recombinant analog of enlimomab, an anti-ICAM-1 (CD54) antibody, produced for research use only and not intended for human or veterinary use. It is built around the same human target, ICAM1 (UniProt P05362), so it can serve as a well-characterized binding reagent for studying ICAM-1 biology and for benchmarking ICAM-1-directed programs. Typical research applications include use as a positive or isotype-matched control, a blocking/neutralizing tool in adhesion and leukocyte-migration assays, a capture or detection reagent, and a reference standard in in-vitro and preclinical characterization work. It is offered at research grade with low endotoxin (generally under 1 EU/mg, with ultra-low-endotoxin options under 0.5 EU/mg) and is available in bulk milligram-to-gram quantities to support assay development, screening cascades, and larger preclinical studies. Because it is supplied unconjugated, it can be paired with downstream labeling or conjugation chemistries for ADC-development workflows, detection, or immobilization as required by the end user.
ICAM-1 (intercellular adhesion molecule 1, CD54; gene ICAM1, UniProt P05362) is a type I transmembrane glycoprotein of the immunoglobulin superfamily, comprising five extracellular Ig-like domains, a transmembrane region, and a short cytoplasmic tail. It is expressed at low basal levels on endothelial cells, epithelial cells, and leukocytes and is strongly upregulated by inflammatory cytokines such as TNF, IL-1, and IFN-gamma. ICAM-1 is a principal counter-receptor for the beta-2 integrins LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18), mediating firm adhesion, leukocyte transendothelial migration, and immunological-synapse formation. It also serves as the cellular receptor for human rhinovirus and for Plasmodium falciparum-infected erythrocytes. Through these interactions ICAM-1 contributes to inflammation, immune-cell trafficking, and tissue injury, making it a long-standing target in ischemia-reperfusion, transplantation, and autoimmune research.
