Description

Description: This 6C4 monoclonal antibody reacts with human CD32 (also known as Fc gamma RII). This antibody recognizes two isoforms of the receptor, Fc gamma RIIA and Fc gamma RIIB. These 40-kDa polymorphic transmembrane glycoproteins are expressed on B cells, granulocytes, monocytes, macrophages, and platelets. Moreover, these receptors are detected on natural killer cells. CD32 enables interaction between Fc gamma RII-expressing cells and opsonized antigen or IgG-containing immune complexes. Both receptors exhibit low affinity towards IgG and play a role in inflammation and autoimmune disease. This clone has been reported to inhibit Ig binding in a rosette blocking assay. Applications Reported: This 6C4 (CD32) antibody has been reported for use in flow cytometric analysis. Applications Tested: This 6C4 (CD32) antibody has been pre-titrated and tested by flowcytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

Experimental details

Fig. 6 Surface expression of key markers of microglia. a Flow cytometry analysis was used to measure the surface expression of CD11b, CD14, CD68, CD16, CD32, CD64, CD163, P2RY12, and TGFbetaR on the representative immortalized cell line hmuglia 1A1. In each experiment, 100,000 cells were resuspended in 1 mL of cold PBS in the presence of 0.5 mug of the antibody or isotype control for 20 min on ice. Appropriate secondary antibodies were used in the absence of fluorophore-conjugated primary antibody, and the cell-antibody complexes were centrifuged and resuspended in PBS. In each FACS profile, the gray distributions represent the proportion of cells bound to the isotype control, whereas the red distributions represent the proportions of cells bound by the target antibody. b Quantification of the abovementioned markers as well as GFAP, CD4, and CCR5 on the surface of primary human astrocytes and immortalized microglia, as indicated
