Specificity of ICAM-1 signal on stimulated and non stimulated media supernatants.
Human PBMCs were cultured in RPMI supplemented with 10% fetal calf serum, 2 mM L-glutamine, 100 U/mL penicillin, and 100 μg/mL streptomycin. Cells were cultured for 2 days at 37⁰C in the presence or absence of PHA. The concentrations of ICAM-1 were interpolated from the calibration curve and corrected for sample dilution. The mean ICAM-1 concentration was determined to be 320 pg/mL in unstimulated PBMC supernatants and 2,654 pg/mL in stimulated PBMC supernatants.

Frequency histogram of ICAM-1 levels in serum of individual normal healthy donors.
The levels of ICAM-1 in serum samples were tested from ten individual healthy donors. Levels were interpolated from the standard curve and corrected for sample dilution. The levels of ICAM-1 are shown for the percentage of individuals within each 100 ng/mL bin center of the distribution. The mean level of ICAM-1 was 469 ng/mL with a range of 347 to 629 ng/mL and a standard deviation of 77 ng/mL.

Comparison of ICAM-1 levels in three Human cell culture lysates.
The levels of ICAM-1 protein were assessed in three Human cell line lysates loaded at 2.5 μg/mL of protein. The raw OD 450 nm signal for each sample was interpolated from an ICAM1 standard curve.

HDL suppresses Aβ-induced monocyte adhesion in engineered vessels via SR-BI. SR-BI blocking antibody was circulated through the lumen of engineered vessels prepared using HUVEC for 1 h prior treatment with 200 µg/mL of HDL for 2 h followed by injection of 1 µM of monomeric a Aβ40 or b Aβ42 within the tissue chamber (abluminal) for 8 h prior to injecting circulating fluorescent THP1 into the lumen. c-d ICAM-1 protein was measured in tissue lysates prepared in RIPA buffer by commercial ELISA. Graphs represent means ± SD of adhered monocytes relative to Aβ treated tissues from at least 4 individual grafts. * and # p < 0.05
Reactivity 정보
제품 세부 정보
Human ICAM1 ELISA Kit (CD54) ab174445 is a rapid single-wash 90-min Sandwich ELISA to measure Human ICAM1 (CD54)in cell culture extracts, cell culture supernatant, citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 1.6 pg/mL.
How the assay works
Human ICAM1 (CD54)SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

ICAM1, is a cell surface glycoprotein typically expressed in endothelial cells and cells of the immune system. The extracellular portion of ICAM-1 forms five immunoglobulin like domains attached to a single hydrophobic transmembrane region and a short cytoplasmic tail. ICAM-1, binds to the Leukocyte Integrins LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18) as well as to non integrin ligands such as CD43, fibrinogen, hyaluronan, Rhinoviruses and Plasmodium falciparum-infected erythrocytes. Binding to LFA-1 facilitates trans-endothelial leukocyte migration to areas of inflammation via promotion of endothelial apical cups assembly.
ICAM-1 expression increases in the vascular endothelium, macrophages and lymphocytes in response to cytokine stimulation (IL-1 and TNF). Furthermore, ligation of ICAM-1 up-regulates its own expression in a positive-feedback loop to maintain a pro-inflammatory environment conducive to leukocytes endothelial transmigration.
Soluble ICAM-1 is reported to be present in normal serum, cerebrospinal fluid, urine and bronchoalveolar lavage fluid. Elevated levels of soluble ICAM-1 have been associated with multiple organ failure, atherosclerosis, autoimmune disorders, diabetes, obesity, hypertension, liver disease as well as cancer, and several studies have correlated serum levels of sICAM-1 with the severity of these diseases.
