CD32 antibody | AT10
Mouse anti Human CD32 antibody, clone AT10 (MCA1075) used for blocking of Fc receptor and inhibition of IC-mediated α ifn production by pDSs
Image caption:
The Fc region of 24F4A enhances the inhibition of immune complex‐induced IFNα production by human pDCs A–F Isolated human pDCs were treated with increasing concentrations of 24F4A (red circles), 24F4A‐ef (black squares), or 10 μg/ml of the isotype control (black triangle) and stimulated with 5 μM of R848 (A and B), 1 μM of CpG‐A (C and D), or immune complexes (E and F) for 16 h at 37°C. IFNα concentrations in cultured supernatants were determined using ELISA. Representative plots for each stimulation (A, C and E) and the average IC50 of 24F4A and 24F4A‐ef for each stimulation condition (B, D and F) are shown (n = 3). Horizontal bars represent mean IC50, and error bars represent SD of the mean from three independent experiments. G. Isolated human pDCs were treated with 10 μg/ml of 24F4A (black line), 24F4A‐ef (gray shaded histogram), or the isotype control (gray dotted line) for 10 min at 37°C. Flow cytometry was used to evaluate pSYK and pPLCγ2. Shown is a representative plot of two independent experiments. H. Isolated pDCs treated with 10 μg/ml of anti‐CD32a (AT10) and stimulated with CpG‐A, R848, or immune complexes. Error bars represent SD of percent inhibition of IFNα from three independent experiments.

Mouse anti Human CD32 antibody, clone AT10 (MCA1075) used as a blocking agent to assess the effect of FcγRs on heparin binding protein (HBP) release by ELISA.
Image caption:
Antibodies against FcγRII inhibit HBP release.
Whole blood (diluted 1∶10) was incubated with antibodies against different FcγRs, isotype control antibodies, or buffer alone, for 20 minutes at 37°C. M1 protein was added and the HBP release was measured. Data are expressed as percentage of release without any antibodies added, and are the mean±SD from three different individuals, each done in duplicate. The different treatment groups were compared using ANOVA, and when found significantly different the treatment groups were compared against the control group using Dunnett's 2 sided test.

Antibody Quality and Performance Guarantee
| Mouse anti Human CD32 antibody, clone AT10 recognizes the human CD32 antigen, a ~40 kDa glycoprotein that acts as a low affinity receptor for IgG (also known as Fc gamma RII). CD32 mediates several functions including endocytosis, activation of secretion, cytotoxicity and immunomodulation. CD32 is expressed by B cells, monocytes, granulocytes and platelets. Mouse anti Human CD32 antibody, clone AT10 blocks the binding of IgG to Fc gamma RII (Larsson et al. 1997). |
