FC - Quality tested

Application Notes:

This clone is reported to have some effect on increasing LFA-1-mediated adhesion and does not block LFA-1 binding1.

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 ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Lymphocyte function-associated antigen 1 or LFA-1 is a heterodimer composed of two members of the integrin family, αL (CD11a) and β2 (CD18).  LFA-1 is expressed primarily on lymphocytes, monocytes/macrophages, and granulocytes.  It is involved in cell adhesion and costimulation processes. The ligands for LFA-1 are ICAM-1 (CD54), ICAM-2 (CD102), and ICAM-3 (CD50).
