CD89 antibody | MIP8a
Mouse anti Human CD89 antibody, clone MIP8a (MCA1824) used to inhibit phagocytosis by human neutrophils in vitro
Image caption:
MIP8a FcαRI blocking antibodies do not stimulate Fc-receptor inhibitory pathways. (A) Human neutrophils were incubated with fluorescent BSA- (white bar) or IgA-coated (red bars) beads. Quantification of phagocytosis is depicted in the presence of anti-FcαRI MIP8a blocking antibodies (whole IgG) or as F(ab′)2. Data of three donors are presented as mean ± SD. Student’s t test; **p <0.01.

Antibody Quality and Performance Guarantee
| Mouse anti Human CD89 antibody, clone MIP8a recognizes the human CD89 cell surface antigen, a 50-75 kDa cell surface glycoprotein that is also known as the IgA receptor (Fc alpha R). CD89 is expressed by peripheral blood monocytes and neutrophils. MIP8a blocks binding of IgA to the Fc alpha R, and also inhibits neutrophil phagocytosis of IgA complexes. |
