Application Notes

ELISA demonstrated C2095 has robust binding to IdeS-generated F(ab')2 fragments of human IgG1 and human IgG4 but does not bind IdeS-generated F(ab')2 fragments of human IgG2. It also does not bind the intact IgG1, IgG2 or IgG4 counterparts (Brezski et al, 2014). ADCC and CDC assays showed C2095 is capable of restoring antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity against WIL2-S cells to the otherwise inactive anti-CD20 IgG1 F(ab')2 fragment. It also reinstated ADCC against MDA-MB-231 cells to an anti-CD142 IgG1 F(ab')2 fragment. This antibody was also capable of eliciting both CDC and ADCC to IgG4 F(ab')2 fragments (Brezski et al, 2014).

Short Description

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