CD23 antibody

BLAST-2; C-type lectin domain family 4, member J; Fc fragment of IgE low affinity II receptor; Fc-epsilon-RII; FCER2; FCER2A; FceRII; IgE-binding factor (IGEBF) ; Immunoglobulin E receptor, low affinity II; Lymphocyte IgE receptor

Positive Control: Tonsil: The follicular dendritic cells of the germinal centres should show a strong CD23 immunostaining while the majority of lymphocytes in the mantle zone of the follicles should show an at least weak staining. Negative Control: Tonsil: The squamous epithelial cells and T-cells in the interfollicular T-zones should not show any CD23 immunostaining. Cellular Localization: Cell surface Protocol Recommendations: Manual Protocol: Freshly cut sections should be used (less than 10 days between cutting and staining) . Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7.8 Target Retrieval Solution buffer. Apply the antibody at a dilution of 1:150 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.
