About RecombiMAb human IgG4 (S228P) isotype control, anti-hen egg lysozyme This human IgG4 S228P isotype control antibody reacts with hen egg lysozyme and has low or no specific binding to any human sample. The S228P mutation is included to prevent IgG4 Fab exchange. This is a recombinant human IgG4 antibody produced in CHO cells. This human IgG4 isotype control antibody differs from CP147 in that CP147 has a kappa light chain and CP181 has a lambda light chain.
