RDI Division of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (flow cytometry, neutralization, blotting, histochemistry, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below. All products are for in vitro research use only-not for use in or on humans or animals-not for use in diagnostics.

SPECIFICITY: CD50 (Icam-3) is the third counter receptor for LFA-1 and is a focal point for leucocyte interactions. The antigen molecule is a N-glycosylated monomer (110kDa) containing intra- chain disulphide bridges which is capable of transducing signals across the plasma membrane. T cell activation with mitogns, anti-CD3 antibodies or PMA results in the phosphorylation of the 5-cytoplasmic serine residues of ICAM-3.

PRESENTATION: Each monoclonal is delivered in a sealed vial at a concentration of not less than 200µg/2ml in phosphate buffered saline containing 10mM sodium azide and 1mg/ml of bovine serum albumin. We recommend that each laboratory determine an optimum working titre for use in its particular application.

STORAGE: Purified monoclonal antibodies are generally stable for long periods at 4oC. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. It is recommended that monoclonal antibodies are aliquotted upon receipt and then stored at -20C. After thawing they should then be used as a stock solution for up to 60 days. Dilute working solutions are best prepared on the day of use.

For research use only. Not supplied for use in human diagnostic or therapeutic procedures

DATA SHEET: mouse anti-human ICAM-3

Catalog#: RDI-ICAM3        $438.00/vial


Package Size: 50 micrograms in 1ml PBS with 1% BSA and 0.01% thimerosal

Species: mouse IgG1


Specificity: This antibody specifically recognizes human ICAM-3 and does not cross with ICAM-1, ICAM-2 or LFA-1. Not tested for other species.

Neutralization: significantly inhibits binding between LFA-1 and ICAM-3.

ICAM3 is a heavily glycosylated transmembrane 124kDa-molecule with 5 extra-

cellular domains. In contrast to ICAM-1 and ICAM-2 it is particularly expressed on

resting lymphocytes, monocytes, and neutrophils. Icam-3 is not found on

endothelial cells.

Together with ICAM-1 and ICAM-2, ICAM-3 acts as a ligand for LFA-1 and binds this B2-

integrin through its 2 N-terminal domains. All three Icams-molecules own distinct

features during the interaction between leukocytes and their different targets. In

this context ICAM-3 is potentially the most important ligand for LFA-1 in the initiation

of the immune response, e.g. the adhesion of resting T-lymphocytes to antigen presenting

B-cells. After immune cell activation the importance of ICAM-3 decreases because ICAM-1

is upregulated to a much greater extent.

An involvement of ICAM-3 in the T-cell mediated lysis of infected cells and the

allogenetic as well as autologous mixed lymphocyte reaction is discussed.

Application: Anti-ICAM-3 can be used to stain acetone fixed cryostat sections or cell smears. The initial dilution is 1:40 to 1:100 (optimal dilution should be determined by the individual lab for each application. -The antibody may also be used in immunofluorescence. -neutralization: significantly inhibits binding between LFA-1 and ICAM-3.

Storage: Store at 4 DEG C.
