Human

Fc epsilon RII (CD23), a low-affinity IgE receptor, is widely expressed on the surface of a number of cell types. Fc epsilon RII mediates numerous IgE-related immune responses. Both membrane and soluble Fc epsilon RII play important roles in allergic responses.

Flow Cytometry: 5x10e5 ficoll prepared human peripheral blood mononuclear cells were washed and preincubated 5 min with 20ul of 250ug/ml human IgG (To block non specific binding) after which they were1.2 washed and incubated 45 min on ice with 80ul of anti-0.2 0. Binding of anti-CD23 antibody to human cell lines 0 10 20 30ug/ml PBL Nalm-6 1 0.8 0.6 CD23 antibody at a concentration of 10ug/ml. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. A net 5% sub population of the cells stained positive with a mean shift of 0.94 log10 fluorescent units when compared to a Mouse IgG1 negative control at a similar concentration.
