Application Notes

In the original publication, this antibody was used in FACS and in vivo functional assays to examine how B cell depletion affects autoimmunity (Ahuja et al., 2007). In other studies, this antibody has been used mainly in FACS, immunofluorescence, and various in vitro and in vivo functional experiments. More recent works employing this antibody have shown, for instance, that enhanced phagocytosis of circulating B cells by Kupffer cells represents an important in vivo mechanism for improved activity of glycoengineered anti-CD20 mAbs (Grandjean et al., 2016), that B lymphocytes limit senescence-driven fibrosis resolution and favor hepatocarcinogenesis in mouse liver injury (Faggioli et al., 2017), and that B cells inhibit the antitumor immunity against an established murine fibrosarcoma (Maglioco et al., 2017).

Short Description

This chimeric human antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
