About RecombiMAb human IgG1 (K214R/L234F/L235E/P331S) isotype control, anti-hen egg lysozyme This human IgG1 isotype control antibody reacts with hen egg lysozyme and has low or no specific binding to any human sample. The K214R/L234F/L235E/P331S mutations in the heavy chain have been shown to reduce engagement with the cell surface receptor FcγR and potential Fc-mediated effector functions.
