Application Notes

This antibody was reported to mediate AQP4-directed antibody-dependent cellular cytotoxicity and complement-mediated lysis in vitro. The binding characterization of this antibody to AQP4 expressed on Human Fetal Astrocyte (HFA) was done by quantitative flow cytometry (PMID: 19938104). Binding of rAb-58 to the M1 and M23 AQP4 isoforms was measured by the fluorescence ratio imaging method (PMID: 21454592). CHO cells expressing M1- or M23-AQP4 when labeled with rAb-58 conjugated to the red fluorophore Cy3 (rAb-58-Cy3), showed rapid internalization of M23-AQP4 than M1-AQP4 when expressed separately in transfected cells. When both isoforms were co-expressed in OAPs in transfected cells, the antibody causes simultaneous cointernalization of M1- and M23-AQP4 isoforms (PMID: 22987455).
