FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1,2, Western blotting1, in vitro and in vivo blocking of tumor cells metastasis or stimulation of cell-adhesion2-6, and immunohistochemical staining7 of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 splenocytes stained with M18/2 PE


CD18 is a 95 kD protein, also known as integrin β2 subunit. It is expressed on all leukocytes. CD18, in association with integrin α chain CD11a, CD11b, and CD11c forms LFA-1, Mac-1, and αXβ2, respectively, and plays an important role in leukocytes adhesion. The CD18 integrin complexes bind ICAM-1 (CD54), ICAM-2 (CD102), ICAM-3 (CD50), iC3b, and fibrinogen. The M18/2 antibody is able to block tumor cell metastasis and enhance cell adhesion.
